As other economists have shown, Gabriel Zucman's tax and inequality data is wildly misleading. He turns seemingly every methodological dial to claim that inequality has soared and high-earner taxes have collapsed. In his own data, virtually the ENTIRE drop in high-income taxes come from Zucman's highly unorthodox assumptions about the incidence of the corporate tax - which he claims cost the top 1% of earners 29% (!) of their income in 1951, and yet now costs them 6%. And this questionable data accounts for his ENTIRE claimed "drop" in higher-earner taxes. You see - on the income tax side - Zucman's own data shows that the average individual income tax paid by the rich has RISEN - not fallen - since the 1950s. See gabriel-zucman.eu/usdina/ then click on "Table 2: Distributional series," and navigate to tab TG2b, column T for income taxes (and column U for corporate taxes) As much as Zucman builds up 1950s income tax rates, almost no one actually paid 91% tax rates - or even touched a tax bracket over 50%. And that's why actual income tax revenues - including income tax rates paid by the rich - were *lower* in the 1950s than today. Zucman's rhetoric is peddling a "tax the rich" utopia of the 1940s-1960s that his own data shows did not exist.
