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

深潮Published on 2025-12-24Last updated on 2025-12-24

Abstract

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originated from Mike Green's "poverty line of $140k" theory in the U.S. It argues that official poverty metrics are outdated, failing to account for soaring costs in housing, healthcare, and childcare, while stagnant wages and reduced welfare benefits create a trap for middle-income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.

03

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.

Related Questions

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.

Hedge Fund Q1 Interpretation: Everyone Is Selling Software, Buying Chips

Hedge Funds and Mutual Funds Aligned in Q1: Dumping Software, Buying Chips A clear consensus emerged among major U.S. hedge funds and mutual funds in Q1: they were simultaneously selling software stocks and pouring capital into the semiconductor sector. This aggressive rotation pushed semiconductor exposure in hedge fund long portfolios to a record high. Hedge funds delivered a 7% return year-to-date, while only 30% of large-cap active mutual funds outperformed their benchmarks. The average short interest for S&P 500 constituents rose to 3% of market cap, the highest since 2011. Within technology, the structural shift was stark. Hedge funds' semiconductor weighting hit an all-time high, while software fell to its lowest since 2019. Excluding Microsoft, mutual funds' relative overexposure to semis vs. software was the largest since 2012. Microsoft was among the most net-sold stocks by both groups. Hedge funds net purchased semiconductor names like LRCX and AMAT. Strategies diverged on leverage and cash. Hedge funds increased their net exposure to near a one-year high after an initial cut. Mutual funds raised their cash allocation, though it remains historically low at 1.4%. Sector alignment was high in Industrials (both overweight) but divergent in Tech: hedge funds increased their Tech net tilt by a record 853 basis points, while mutual funds reduced theirs. Clear splits also appeared in Financials and Consumer Discretionary. Four stocks appeared on both Goldman's hedge fund VIP and mutual fund overweight lists: BA, MA, MRVL, and V. This "shared favorites" basket has returned 10% YTD, outperforming the equal-weight S&P 500. Notably, all "Magnificent Seven" stocks are on the hedge fund VIP list but are uniformly underweighted by mutual funds.

The Evolution Path of Physical Bitcoin

The Evolution of Physical Bitcoin Bitcoin's digital nature is its core strength, enabling self-custody and rapid global transfers. However, its intangibility also hinders mainstream adoption. For over a decade, creators have attempted to materialize Bitcoin while preserving its cash-like properties, yielding notable results. Casascius Coins, launched in 2011, were the first and most iconic physical Bitcoin. Creator Mike Caldwell generated private keys offline, printed them on coins, and sealed them with tamper-evident holograms. This model relied on user trust in the centralized issuer. Production ceased in 2013 due to regulatory pressure from FinCEN. RavenBit Coins emerged in 2014 aiming to decentralize minting by letting users generate and apply their own keys. However, this led to trust issues with numerous untrusted minters and insecure key generation methods. In 2016, Coinkite introduced Opendimes—a breakthrough in bearer asset technology. These USB-shaped devices generate and store keys internally. Funds can be received by checking the public key, but spending requires physically breaking the device to extract the private key. While innovative and open-source, its cost (~$20) and form factor limit its use for small, everyday transactions. Satochip's Satodime, a card-shaped device using similar secure chip technology, followed. It supports NFC interaction and comes in various forms. While potentially cheaper in bulk (~13€), it remains a high-security hardware wallet, not a low-cost cash substitute. A fundamental cost barrier exists. For physical Bitcoin to achieve widespread commercial use, hardware costs must drop below $1 to match the production cost of fiat banknotes. Current secure chips capable of running Bitcoin's cryptographic algorithms (like secp256k1) are too expensive. Chips like NXP's NTAG X DNA (~$3) show cost-reduction potential but lack native Bitcoin curve support. Projects like OfflineCash embed chips in banknote-like paper, but face challenges with durability, the need for custom Bitcoin-enabled chips, and the inherent requirement for users to verify balances online—which conflicts with Bitcoin's trustless ideal. Coinkite's Tapsigner, a ~$20 card with a proprietary Bitcoin NFC chip, is seen as a more practical step forward. It functions as a reloadable hardware wallet for contactless payments, solving the "change" problem and focusing on real-world retail integration, a direction also pursued by companies like Cash App and Square. In summary, the journey to physical Bitcoin has progressed from trusted centralized mints (Casascius) to user-generated keys (RavenBit) and finally to self-contained secure hardware (Opendimes, Satodime, Tapsigner). The core challenge remains developing a sufficiently low-cost, durable, and truly trustless physical bearer asset that can function like cash in daily transactions. Current solutions are either too expensive or introduce new trust assumptions, keeping the ideal of ubiquitous physical Bitcoin just out of reach for now.
