The three convenient and accurate Wikipedia graphs below show the details. The first graph compares the official tax rates paid by the top and bottom income earners. Notice especially that from the end of World War 2 into the early 1960s, the highest income earners paid a tax rate over 90% during many years. Today, the top earners pay a rate of only 35%. Notice also how the gap between the rates paid by the richest and the poorest has narrowed. If we take into account the many loopholes the rich can and do use far more than the poor, the gap narrows even more.
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 the graph above: (1) 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 (2) those tax-the-rich years after 1945 experienced far lower unemployment and far faster economic growth than we have had for years.
The lower taxes they got for themselves are one reason why the rich 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 characterized the US a century ago.
