When the Cadillac Eldorado made its debut in the 1950s, wealthy Americans were paying a top rate of tax of 90%; today, the top rate of tax is 35%.
One conclusion is clear and obvious: the richest Americans have dramatically lowered their income tax burden since 1945, both absolutely and relative to the tax burdens of the middle income groups and the poor.
Consider two further points based on this graph: first, if the highest income earners today were required to pay the same rate that they paid for many years after 1945, the federal government would need far lower deficits to support the private economy through its current crisis; and second, those tax-the-rich years after 1945 experienced far lower unemployment and far faster economic growth than we have had for years.
Historical tax rates for the highest and lowest income earners
The lower taxes the rich got for themselves are one reason why they have become so much richer over the last half century. Just as their tax rates started to come down from their 1960s heights, so their shares of the total national income began their rise. As the two other Wikipedia graphs below show, we have now returned to the extreme inequality of income that characterised the US a century ago.
