More than half the increase in the top 1% income share since 1985 flowed through pass-through businesses to ~ 3mm private business owners with a mean net worth of ~$25mm.
Did most of the top 1% income gain come from private businesses?
Core argument: Owen Zidar and Eric Zwick find that 5.8 of the 10.5 percentage-point rise in the U.S. top 1% income share since 1985 flowed through pass-through businesses, more than half of the increase.
The income that lifted America's top 1% did not come mainly from tech or Wall Street, according to Owen Zidar and Eric Zwick. More than half of the rise in the top 1% income share since 1985, 5.8 of 10.5 percentage points, flowed through pass-through businesses. Zidar and Zwick, counted roughly 3 million wealthy private business owners, with average net worth near $25 million, running law firms, car dealerships, medical practices, commercial contractors and regional restaurant chains, the kind of businesses that make their owners wealthy and well known in their own communities without ever making them nationally famous.

What’s Missing in the Fed’s Data about Ultrarich Portfolios— The Federal Reserve's Distribution of Financial Accounts defines "private business" narrowly as proprietor's equity in noncorporate, nonfinancial businesses, excluding S-corporations, other private corporations, and private equity and hedge fund partnerships, which are lumped into "corporate equities." The Survey of Consumer Finances instead shows private business is roughly 45–50% of top 0.1% wealth.
They’re Rich but Not Famous—and They’re Suddenly Everywhere— An analysis of Federal Reserve data estimates about 430,000 U.S. households are worth $30m or more, including roughly 74,000 worth at least $100m, with growth in the number of very rich households outpacing overall population growth over recent decades. Nearly 72% of the top 0.1%'s wealth consists of corporate equities, mutual fund shares, and private businesses.
Capitalists in the Twenty-First Century— Most income at the top of the US distribution is non-wage income, primarily profits from closely-held, mid-market firms in skill-intensive industries owned by working-age individuals. The authors find private business profit falls by three-quarters after an owner retires or dies prematurely, indicating most top earners are "working rich" deriving income from human capital.
AI Summary.Census data show the number of U.S. families with inflation-adjusted incomes above $150,000 grew from under 3m in 1967 to over 31m in 2025, while families earning under $75,000 fell by almost 3m in absolute terms.

In 1967, just 5.5% of American families had an inflation adjusted income of $150,000 or more. In 2025, 35.7% did. During that timeframe, the share of families with a real income less than $75,000 declined from 63.4% to 32.8%.
Are more American families reaching higher inflation-adjusted income levels?
Core argument: The number of U.S. families with incomes above $150,000 in 2025 inflation-adjusted dollars rose from fewer than 3 million in 1967 to over 31 million in 2025, according to Census data.
In 1967 there were fewer than 3 million families with incomes over $150,000 (in 2025 inflation-adjusted dollars). By 2025, that had grown to over 31 million families. If we look at the highest income threshold in this Census data — over $200,000 — the number of families has grown from just 1 million in 1967 to over 20 million in 2025. And there are fewer lower-income families too: the number of families under $75,000 shrunk, not just as a proportion of the total but even in absolute terms by almost 3 million families from 1967 to 2025. Of course, some of these families do have more earners than in 1967, though we shouldn’t overstate that too much. Using other data from Census, we can see that the share of families with multiple earners hasn’t increased much since 1967, and especially hasn’t since the mid-1990s.

AI Summary.The authors estimate the heritability of labor market outcomes by comparing the excess similarity of same-sex over opposite-sex twins with the corresponding difference among ordinary siblings. They caution that social interaction between twins, assortative mating, genetic dominance, population stratification, or indirect parental effects can bias such estimates upward or make them reflect non-genetic influences.

Analysis of 44,500 twin pairs suggests ~one-third of the variation in log earnings is due to genetic differences – likely an upper bound, because same-sex twins may influence one another and share more similar environments than ordinary same-sex siblings.
How reliable are twin-based estimates of heritability in earnings?
Core argument: The authors identify heritability of U.S. labor market outcomes from a difference-in-differences comparing same-sex versus opposite-sex twins against the corresponding difference among ordinary siblings, adjusting for the estimated share of same-sex twins who are identical.
Our model identifies heritability from the difference-in-differences of same-sex vs. opposite-sex twins vs. siblings. [Specifically], the model attributes to genetic differences the excess similarity of same-sex over opposite-sex twins over and above the corresponding difference among ordinary siblings, adjusting for the estimated share of same-sex twins who are identical. The ordinary-sibling comparison is intended to remove family influences that differ between sons and daughters. Social interactions may lead to an over-estimate of the genetic component in earnings. The estimated heritability of outcomes may be biased in the presence of assortative mating, genetic dominance, population stratification, or violations of the assumption that the home environment is shared to the same degree for MZ as for DZ twins. Even when estimated without bias, heritability need not indicate direct genetic effects – it also may reflect indirect or cultural effects (e.g., effects of the parents’ genes on a child’s outcomes, not operating through the child’s own genes. Twins may [also] influence each other directly – for example in their choice of jobs -- inflating the correlation in their outcomes.

The Inheritance Of Social Status: England, 1600 to 2022— Using a genealogical database of 422,374 English people with rarer surnames, the authors find social status persists strongly even among distant relatives, with status correlations declining by a constant factor of 0.79 per step in the lineage across all status measures and eras studied. The authors argue this constancy suggests social interventions have modest effects.

They attribute about 50% of this to transmitted genes and the rest to environmental pathways.

Core argument: Nearly two-thirds of New York City's real income growth between 2019 and 2024 accrued to the top 1%, compared with under 40% nationally, a result that holds when volatile capital gains are excluded.
Between 2019 and 2024, the New York City’s income shares at the top of the distribution rose faster than the nation's, and nearly two-thirds of the real income growth over the period accrued to the top 1%, compared with under 40% nationally. The result also holds when volatile capital gains are excluded. Real median income fell over the period, and real average income for the bottom 90% of tax units was essentially flat. Adjusted for local prices (but not for transfer programs), the purchasing power of income for the lower 90% of New Yorkers is close to one-fifth below that of the bottom 90% nationally. The divergence at the top is predominantly a story of non-wage income. Wage and salary income shows a much milder widening, and occupational wage data that exclude bonuses show base pay growing faster in lower-wage occupations than in higher-wage ones, and within many occupational groups wages are converging rather than growing more unequal.

The Post‑COVID Decline in the Labor Share— The share of US national income paid to workers fell 1.6 percentage points below its pre-pandemic level, reaching a post-war low.

Core argument: After-tax wage growth reached 5.2% YoY for lower-income households and 4.2% YoY for middle-income households in July, which the Consumer Checkpoint analysis views as one factor behind the narrowing spending growth gap across income cohorts.
We have discussed the “K-shaped” divide between higher- and lower-income households’ spending and wage growth. But since May, our data has shown a significant narrowing in this gap. As of July, spending and wage growth have largely converged across income cohorts, with the exception of the top 5% of earners, who continue to outpace the rest. A similar dynamic was evident in discretionary spending. In our view, one factor behind the narrowing spending growth gap is stronger after-tax wage growth. For lower- and middle-income households, after-tax wage growth rose to 5.2% YoY and 4.2% YoY, respectively, in July.
