The answer depends on which wealth measure, population group, and historical dataset is used. Some estimates place the wealth share of the very richest Americans near early-20th-century levels, while broader measures such as the top 1% share are more mixed.

The answer depends on which wealth measure, population group, and historical dataset is used. Some estimates place the wealth share of the very richest Americans near early-20th-century levels, while broader measures such as the top 1% share are more mixed.
The claim asks whether U.S. wealth inequality has reached levels comparable to those that existed before the 1929 stock market crash and the Great Depression. In public debate, this is often framed as whether the concentration of wealth among the richest households has returned to the levels of the Gilded Age or the Roaring Twenties.
The claim is not a single statistic. It can refer to the share of total household wealth held by the top 10%, top 1%, top 0.1%, or top 0.01%; to wealth Gini coefficients; or to ratios between high-wealth and median-wealth households. These measures can move differently over time.
The phrase "pre-1929 levels" also requires a baseline. Some researchers compare today with 1928 or 1929, while others compare with the broader period before the Great Depression, such as 1913-1929. The available historical data are reconstructed from tax records, estate records, surveys, and national accounts, so estimates are sensitive to methodology.
Research on long-run U.S. wealth concentration generally shows a high level of wealth inequality in the early 20th century, a substantial decline from the New Deal through the mid-20th century, and a renewed rise beginning in the late 20th century. That broad pattern appears across several major studies, though the size of the rebound differs.
For the very top of the distribution, especially the top 0.1% or top 0.01%, some estimates suggest that wealth concentration in the 2010s and early 2020s approached or matched levels associated with the 1910s and 1920s. These findings are often based on capitalization methods that infer wealth from capital income reported on tax returns.
For the top 1% as a whole, the comparison is more mixed. Some series show the top 1% share rising sharply but still below the highest pre-Depression levels; other approaches put it closer to early-20th-century values. Federal Reserve data starting in 1989 confirm a large modern increase in wealth concentration but cannot by themselves determine the comparison with the 1920s.
The assessment also changes if the focus is on income inequality rather than wealth inequality. Income concentration has also risen, but the question here concerns wealth, which includes assets such as real estate, corporate equity, pensions, and privately held business wealth minus debts.
The largest uncertainty is measurement. Wealth is harder to observe than income, especially for privately held businesses, trusts, offshore assets, capital gains, and very high-net-worth households. Different methods allocate pension wealth, housing, and business equity differently, which can change estimates of top wealth shares.
Historical comparisons before 1929 are also less precise than modern estimates. Tax systems, household structure, asset ownership, pensions, and financial markets changed substantially over the last century, so matching categories across time is difficult.
A cautious reading is that U.S. wealth concentration has risen to levels that are historically high by postwar standards, and some measures for the very richest households are near pre-1929 estimates. Whether the overall level of U.S. wealth inequality has fully reached pre-1929 levels remains dependent on the metric and dataset chosen.
The umbrella claim is actually several claims bundled into one. Each needs its own evaluation.

The current evidence leans one way. But we're not committed to the conclusion, we're committed to the evidence.
U.S. wealth inequality has likely reached levels comparable to those before 1929 for certain measures, but not universally across all major indicators. Confidence: 80% The claim is supported by evidence from va...
U.S. wealth inequality has risen sharply since the 1980s yet has not returned to pre-1929 levels on every major metric; the top 0.1 percent share approaches some capitalized-income estimates from that era while...

The claim that U.S. wealth inequality has reached levels last seen before 1929 is partially true but depends heavily on the metric and dataset used. For the top 0.1% or 0.01% of households, some estimates (e.g....
Incomplete response: output limit reached before the answer finished.
The claim is partially true but overstated as a blanket statement. The most defensible answer is: by some measures focused on the very top of the distribution, U.S. wealth concentration has approached pre-1929 levels, but it has not unambiguously returned to or surpassed those levels across all measures. Confidence: Moderate (about 70%) on the nuanced version; low confidence (around 25%) that the strong version ("reached pre-1929 levels" across the board) is correct. Key evidence: - Saez and Zucman (2016, QJE), usi...

Incomplete response: output limit reached before a parseable answer.
The claim is partially true but depends heavily on the specific measure of wealth inequality used. For the very richest households (top 0.1% or top 0.01%), their share of total wealth has indeed returned to levels comparable to the late 1920s. However, broader measures such as the top 1% share or the Gini coefficient remain below their pre‑1929 peaks in most estimates, so the claim does not hold across all major metrics. Confidence: High. Key evidence: - According to Saez and Zucman (2016, *Quarterly Journal of Eco...
