In an op-ed for the NY Times, Warren Buffett proposes a minimum tax on high incomes, specifically “30 percent of taxable income between $1 million and $10 million, and 35 percent on amounts above that”. He argues that higher tax rates will not curtail investment activity.
Between 1951 and 1954, when the capital gains rate was 25 percent and marginal rates on dividends reached 91 percent in extreme cases, I sold securities and did pretty well. In the years from 1956 to 1969, the top marginal rate fell modestly, but was still a lofty 70 percent - and the tax rate on capital gains inched up to 27.5 percent. I was managing funds for investors then. Never did anyone mention taxes as a reason to forgo an investment opportunity that I offered.
Under those burdensome rates, moreover, both employment and the gross domestic product (a measure of the nation’s economic output) increased at a rapid clip. The middle class and the rich alike gained ground.
