From the "$140k Poverty Line" to the "Middle-Class Execution Line": To Survive or To Live with Dignity?

深潮Publicado a 2025-12-24Actualizado a 2025-12-24

Resumen

The article discusses the viral narrative of the "middle-class kill line" (斩杀线), which originated from Mike Green's "poverty line of $140k" theory in the U.S. It argues that official poverty metrics are outdated, failing to account for soaring costs in housing, healthcare, and childcare, while stagnant wages and reduced welfare benefits create a trap for middle-income earners. As incomes rise, families lose eligibility for subsidies but face higher expenses, leading to a net decrease in disposable income—a phenomenon likened to a "kill line" in gaming where a threshold triggers financial collapse. The piece attributes this to structural issues like Baumol’s cost disease, where service-sector inefficiencies drive up prices, and critiques Green’s data inaccuracies while acknowledging the visceral reality of economic strain. It contrasts the U.S. situation with China, where service costs are suppressed, avoiding a similar "kill line" but at the cost of service-sector dignity and conditions. The conclusion underscores that economic trade-offs are inevitable.

The narrative of the "execution line" first caught my attention in November within X and Substack circles. It originated from Mike Green's "$140k poverty line" theory, which went viral in the United States. I never expected that over a month later, this narrative would spread and mutate into the "execution line" in China, which is quite fascinating.

It's a pity my AI narrative radar (see here) wasn't ready at that time; otherwise, I would have loved to see if AI could track the spread and evolution of this narrative.

01

At the end of November, I read three articles by Mike Green on Substack:

These are three extremely long articles that make you feel like you're reading forever; the three combined have the word count of a small book.

I'll try to summarize them in plain language as follows:

The gist of the articles is: If you feel like the current economic data looks good, but your daily life is tight, and an annual salary of $100,000 still leaves you feeling poor, it's not your fault. It's because the ruler used to measure wealth and poverty is like Doraemon's self-deceiving ruler.

The articles present three main points:

1. The "Poverty Line" is actually like marking the boat to find the sword (a Chinese idiom meaning a futile approach).

The official U.S. poverty line is an annual income of $31,200 for a family of four; as long as your income exceeds $30,000, you are not considered poor.

But this ruler was created in 1963. The logic back then was simple: a family spent about one-third of their money on food, so by calculating the minimum food cost and multiplying it by 3, you got the poverty line.

But the situation is vastly different now. You've probably all seen that famous chart—"Baumol's Cost Disease":

Food has become cheaper, but the costs of housing, healthcare, and childcare have skyrocketed. If you recalculate based on the 1963 standard of living—meaning the ability to normally "participate" in society (having a place to live, a car to drive, childcare, and access to healthcare when sick)—the real poverty line today is not $30,000-plus, but $140,000 (approximately 1 million RMB), just to live decently in this society.

2. The harder you work, the poorer you become.

There's a huge bug in the design of the U.S. welfare system: When your annual salary is $40,000, you are officially poor. The state gives you food stamps, covers your healthcare (Medicaid), and subsidizes childcare costs. Life is tight but there's a safety net.

But when you work hard and your salary increases to $60,000, $80,000, or even $100,000, disaster strikes: Your income is higher, but the welfare benefits are gone. Now you need to pay for expensive health insurance and rent in full.

The result is: A family with an annual income of $100,000 might have less disposable cash left at the end of each month than a family with an annual income of $40,000 (receiving welfare).

This is the origin of the "execution line" and the "execution line specifically targeting the middle class" narrative on Chinese social networks: Just like in a game where your health drops to a certain threshold and you get instantly killed by a skill, a one-hit KO; the middle class, stuck in the middle,刚好 step onto the node where welfare withdraws, tax burdens increase, and all kinds of rigid expenditures (health insurance, rent, childcare, student loans) fully press down. They lose subsidies while bearing high costs. Once they encounter unemployment, illness, or rent increases, they are locked in by the execution line.

3. The assets you own are actually quite inflated.

Because:

Your house is not an asset; it's prepaid rent: Did you get richer if your house appreciated from $200,000 to $800,000? No. Because if you sell it, you still have to spend $800,000 to buy a similar house to live in. You haven't gained additional purchasing power; your cost of living has just increased.

The inheritance you're waiting for is not a wealth transfer: The inheritance from the Baby Boomer generation won't be passed on to you; it will be passed on to nursing homes and the healthcare system. Nursing care (dementia care, nursing homes) in the U.S. now costs $6,000 to over $10,000 per month. An $800,000 house owned by parents will most likely turn into medical bills, collected by medical institutions and insurance companies.

Your class has become a caste: In the past, you could跨越阶级 through hard work. Now it depends on "admission tickets"—Ivy League degrees, recommendation letters from core circles. The inflation rate of these "assets" is even higher than that of houses. So an annual salary of $150,000 might allow you to survive, but it can't buy the ticket for your children to enter the upper class.

02

What exactly caused the great inflation of the U.S. poverty line (or, in our context—the great shift of the "execution line")?

Mike Green attributes it to three turning points in U.S. history:

Turning point 1: The deterioration and monopolization of unions in the 1960s, leading to decreased efficiency and increased costs.

Turning point 2: The great antitrust shift in the 1970s, where large companies疯狂兼并, controlled the market, and suppressed wages.

Turning point 3 (which everyone can probably guess): The China shock. But the article's viewpoint is not that China forcibly took away jobs, but that U.S. capitalists engaged in capital arbitrage—moving almost all factories away from the U.S. to profit from the differential.

But Teacher Green didn't just kill and not bury; he finally proposed a very hardcore solution called the "Rule of 65." The core idea is very familiar to us Chinese: "Fight the local tyrants and distribute the land"—(1) Increase taxes on corporations (but exempt investments from taxes); (2) Prevent large corporations from deducting interest on borrowed money for tax purposes,坚决打击 financial空转; (3) Reduce the burden on the workhorses:大幅降低 the payroll tax (FICA) for ordinary people, putting more cash in their hands. Where does the missing money come from? Make the rich pay more, remove the cap on social security taxes for the wealthy.

Chinese experience is absolutely practical.

Teacher Mike Green's views刷屏 enthusiastically among the U.S. middle-class masses. But it aroused collective resistance from the elite class and various economists.

There are indeed many data flaws in his articles. For example, using data from affluent areas (Essex County, top 6% in U.S. housing prices) as the national average; assuming all children go to expensive daycare centers (over $30,000 per year), while in reality most American families still take care of their own children; some concepts are also somewhat混淆, such as equating "average expenditure" with "minimum survival needs."

Later, Green went on many podcasts to explain himself: This $140,000 does not refer to the traditional poverty of "not having enough to eat," but rather the "decent living threshold" for an ordinary family to live without relying on government subsidies and still save some money.

Although Teacher Green's math seems to be indeed miscalculated, the critics didn't win either, because regardless of what the exact poverty line is, people's "feeling of poverty" is very real. And the "feeling of being executed" is becoming more and more real—whether for Americans or Chinese.

Why? I think the real reason is still "Baumol's Disease."

"Baumol's Cost Disease" was proposed by economist William Baumol in 1965 to describe an economic phenomenon:

Some industries (like manufacturing) rely on machines and technology, becoming more and more efficient, with unit costs getting lower and lower; but some industries (like education, healthcare) rely mainly on people, and efficiency is difficult to significantly improve—one lesson still takes an hour, one doctor seeing one patient also takes time, impossible to speed up multiples like a factory.

So here's the problem: Wages across society will rise along with those high-efficiency industries. To prevent teachers and doctors from jumping to higher-paying industries, schools and hospitals also have to raise wages. But their efficiency hasn't improved much, yet wages have risen, resulting in higher and higher costs and prices rising accordingly.

In other words: Industries that can be sped up by machines have lifted overall wages. Industries that cannot提速 have to raise salaries to retain people, but efficiency hasn't changed, so they become more expensive. This is "Baumol's Cost Disease."

This is why on the chart at the beginning of the article: The lines representing industrial goods like TVs, phones, and toys go downward, becoming cheaper and cheaper; while the lines representing education, healthcare, and childcare costs soar.

The logic behind this is actually very realistic:

In any field that can be replaced by machines and automation, efficiency will only get higher. For example, mobile phones, although the price doesn't seem to have dropped much, their performance is worlds apart from a few years ago, with computing power and storage multiplying several times. This is essentially a kind of "invisible price reduction" brought by technology. Not to mention Chinese manufacturing, photovoltaics, EVs, and lithium batteries, where automation is increasing, and costs are driven straight to the floor price.

But the problem lies in those places where "machines cannot replace people." When I was little, the nanny who took care of me could look after four kids by herself. Even today, she can still only look after four at most, and because today's parents have higher demands, she might even be able to look after fewer children. This means that the production efficiency of the service industry hasn't changed for decades, and has even regressed.

However, the service industry (specifically in the U.S.) has to raise wages for nannies and nurses to prevent them from running off to deliver food or work in factories. They have to keep up with the income level of the whole society. The coffee beans in a coffee shop aren't worth much, but the exorbitant price you pay is mostly for the staff's labor, rent, and utilities. Efficiency hasn't increased, but wages have to rise, so the cost can only be passed on to consumers. (Note: This specifically refers to the U.S.)

Therefore, the American middle-class families being "executed" are not poor to the point of not having enough to eat. They have cars, iPhones, and various video memberships, but when facing "service-based expenditures" like buying a house, seeing a doctor, or raising children, their wallets are instantly emptied. So, it's not that the American people have truly become poorer; it's that the American people's money becomes less and less sufficient in the face of those "inefficient but outrageously expensive" services.

Writing here, I know everyone has been wanting to ask: Does China have an execution line? Does China's execution line execute the middle class? Has China's poverty line also become higher?

The answer is most likely no.

So our "execution line" might not appear. I discussed this with Dean Liu in the "Wall Crack Forum" podcast episode: "When China Becomes an Industrial Cthulhu, What's Left of Trade? Higher Productivity, Why Lower Wages?"

The situation in China, we Chinese should all know: Chinese society is more sensitive to service prices. For things that are not "production tools," people are generally unwilling to pay, especially for services. In the expenditure structure of labor force reproduction, certain service expenditures have been长期压得很低 in China, even to the extent that "this part of the wage doesn't have to be paid." When services are undervalued and the welfare stage is different, the wage system naturally presents a structure completely different from the West.

This creates a奇妙的现象: One can always "survive" no matter what. Because the cost of living can be pressed extremely low.

Therefore, China might not have an "execution line," but that doesn't mean there isn't an invisible threshold. For example, how low can the dignity of service providers be pressed? How high can the intensity be raised?

So it still comes back to that saying: Everything comes at a cost.

Preguntas relacionadas

QWhat is the origin of the '140k poverty line' narrative discussed in the article?

AThe '140k poverty line' narrative originated from Mike Green's theory, which went viral in the United States. It argues that the official U.S. poverty line of $31,200 for a family of four is outdated (based on 1963 standards) and that the actual income needed for a family to live decently without government assistance is around $140,000, due to soaring costs in housing, healthcare, and childcare.

QHow does the 'killing line' metaphor apply to the middle class according to the article?

AThe 'killing line' metaphor describes a threshold where middle-class families, despite earning higher incomes (e.g., $100,000 annually), lose government benefits while facing high costs for healthcare, childcare, and housing. This leaves them with less disposable income than lower-income families receiving welfare, making them vulnerable to financial collapse from events like job loss or illness.

QWhat is 'Baumol's Cost Disease' and how does it explain rising costs in certain sectors?

ABaumol's Cost Disease, proposed by economist William Baumol in 1965, explains that sectors like education and healthcare rely heavily on human labor and cannot easily increase efficiency. As wages rise across the economy (driven by efficient sectors like manufacturing), these less efficient sectors must also raise wages to retain workers, leading to higher costs for services like childcare and healthcare without proportional productivity gains.

QWhy does the article suggest that China might not have a 'killing line' for the middle class?

AThe article suggests China might not have a 'killing line' because Chinese society is highly sensitive to service prices and often unwilling to pay for non-essential services. Labor costs in sectors like childcare and healthcare are suppressed, allowing living costs to remain very low. This means middle-class families can 'survive' without facing the same financial thresholds as in the U.S., though it comes at the cost of service quality and worker dignity.

QWhat solutions does Mike Green propose to address the 'poverty line inflation' in the U.S.?

AMike Green proposes a 'Rule of 65' solution, which includes: (1) Increasing taxes on corporations (but exempting investments), (2) Eliminating tax deductions for corporate borrowing to curb financial speculation, and (3) Reducing payroll taxes (FICA) for ordinary workers to increase disposable income, funded by removing the Social Security tax cap for high earners.

Stocks Are Plummeting More Sharply Than Cryptocurrencies. Where Has the Money Gone?

Stock Markets Plunge Deeper Than Cryptocurrencies: Where Did the Money Go? In late July, Seoul's Kospi index triggered circuit breakers for two consecutive days, plummeting over 40% from its June high. The collapse was led by heavyweight stocks like SK Hynix, whose record profits still disappointed investors, and devastating leveraged ETFs, with one major product losing over 83% of its value. This signaled a global, forced deleveraging targeting the most crowded trades. Interestingly, while stocks exhibited extreme volatility akin to crypto markets, Bitcoin rose nearly 15% in July after a prior steep drop. Analysis shows the money fleeing equities did not flow into Bitcoin. Instead, Bitcoin had already absorbed its sell-off in May-June, when U.S. spot Bitcoin ETFs saw historic outflows. The true safe-haven beneficiary was gold, whose price rose over 20% year-on-year, highlighting a decoupling between Bitcoin and gold as "digital gold." The sell-off was a targeted unwinding of leveraged positions in tech and semiconductors, accelerated by broker-dealer risk management and shifts in the AI narrative, including new competition from Chinese memory chipmakers. The retreat path was clear: from high-valuation tech stocks to cash and U.S. Treasuries, then to gold. For Bitcoin to attract sustained institutional inflows, conditions like eased global liquidity pressure, a "soft-landing" Fed rate cut, and U.S. regulatory clarity via legislation like the stalled CLARITY Act are needed. Currently, Bitcoin is not a safe haven but an already-cleared asset. Its low correlation with tech stocks, however, makes it a potential diversification play for institutional portfolios once the storm passes. The money isn't here yet, but the positioning is underway.

In Conversation with Ray Dalio: We Are Currently in an AI Bubble, with 1% of My Portfolio in Bitcoin

Ray Dalio, founder of Bridgewater Associates, warns in an interview that the current AI boom shows classic bubble characteristics, which could lead to significant economic downturns as seen in past cycles like 1929 or 2000. He explains that speculative enthusiasm, fueled by debt and overvaluation, often precedes a crash when rising rates or taxation force asset sales, causing widespread losses and recession. Dalio also outlines his "Big Cycle" theory, describing an approximate 80-year pattern where widening wealth gaps, massive government deficits, and shifting geopolitical power (like China's rise) create internal conflict and global instability. He emphasizes that we are in a late-cycle, transitional phase where traditional powers like the US and UK face decline. For personal wealth protection, Dalio advises diversification beyond cash into assets like stocks, bonds, real estate, and particularly gold, which he prefers over Bitcoin. While he holds about 1% of his portfolio in Bitcoin as a non-printable hard asset, he views gold as more secure from technological or governmental threats. Regarding AI's impact, Dalio believes it will disproportionately benefit capital owners, worsening inequality by replacing both physical and cognitive labor. He suggests that human intuition and emotional intelligence, combined with AI, will be key for future workers. On taxation, Dalio argues that wealth taxes are impractical and risk triggering asset sell-offs, reducing productive investment. He points to the UK as a cautionary example of debt, low productivity, and political strife. Geopolitically, Dalio foresees a more regionalized world, with the US showing weakness in prolonged conflicts like with Iran, akin to past imperial declines. The ideal outcome, he suggests, is coexisting powerful blocs (e.g., Americas, China-Asia Pacific) without major war.

Daily 7.2 Trillion KRW: Foreign Capital's Record Net Buying on Friday! Wall Street Says Headwinds for Korean Stock Fund Flows Have Subsided

South Korean stock market sees a dramatic shift in fund flows. On July 31, foreign investors made a record net purchase of approximately KRW 7.2 trillion in KOSPI stocks, marking a fundamental reversal from the persistent large-scale net outflows seen in previous months. This contributed to a significant narrowing of foreign net selling in July to KRW 9.8 trillion, down sharply from KRW 48.4 trillion in June and KRW 44.5 trillion in May. Simultaneously, domestic institutional pressure eased. South Korean pension funds and asset managers turned to a net buying position in July, purchasing KRW 1.0 trillion worth of KOSPI shares, contrasting with net sales in May and June. Market volatility is expected to be dampened by new financial regulations. Effective July 31, the Financial Services Commission tightened access for retail investors to single-stock leveraged ETFs by raising the minimum cash deposit requirement. Trading volumes for these products subsequently dropped to about 50% of their monthly average. Citigroup Research maintains its year-end KOSPI target of 10,000 points. The firm cites several supportive factors: the substantial easing of headwinds from capital outflows, a robust fundamental outlook for the semiconductor sector, historically low market valuations, strong economic fundamentals, and the potential for policy support from financial authorities if needed.
