Conservatives claim that taxes in America are too high. Cross-national data and historical data from the United States raise serious doubts about this claim. As a percentage of GDP, the tax burden in America is low compared with many other advanced capitalist countries. Tax rates for individuals and corporations in America are also comparatively low. Yet conservatives have long complained that taxes in America are too high regardless of historical fluctuations in the tax burden and tax rates, and regardless of economic and geopolitical circumstances. Nowadays, about half of Americans believe that their own taxes are too high. Yet the overwhelming majority feel that taxes on corporations and the rich are too low and that they should be paying more, not less in taxes. Republicans and especially wealthy Republicans are the most likely to be concerned that taxes on corporations and the affluent are too high.
