Sowell states that "no such theory has been found in even the most voluminous and learned histories of economic theories." That's from a scholar who has published extensively in the history of economic thought. Several years ago, Sowell, in his syndicated column, challenged anyone to name an economist from any economic school of thought who had actually advocated a "trickle down" theory. To date, no one has quoted any economist who ever advocated such a theory. Trickle down is a nonexistent theory. Those who use it simply argue against a caricature rather than confront an argument actually made.
President Barack Obama recently criticized Mitt Romney and Paul Ryan for trying to sell a tax plan, which he called "trickledown snake oil." Criticizing tax cuts as trickle down is a way not to confront the argument; however, there's empirical evidence about the effects of tax cuts. Sowell shows that during the Warren Harding administration, in 1921, Secretary of the Treasury Andrew Mellon advocated tax rate cuts, which were enacted into law by Congress. Afterward, there was rising output; unemployment plummeted; and the resulting higher income produced greater federal tax revenues, even though the tax rate had been lowered. There were somewhat similar results in later years after high tax rates were cut during the John F. Kennedy, Ronald Reagan and George W. Bush administrations.
The facts about the 1920s tax rate cuts are unmistakably clear for those who bother to check the facts. In 1921, when the tax rate on people earning more than $100,000 a year was 73 percent, the federal government collected a little more than $700 million in income taxes, of which 30 percent was paid by those earning more than $100,000. By 1929, after the tax rate had been cut to 24 percent on incomes higher than $100,000, the federal government collected more than $1 billion in income taxes, of which 65 percent was collected from those with incomes higher than $100,000.
In 1962, Democratic President John F. Kennedy pointed out that "it is a paradoxical truth that tax rates are too high today and tax revenues are too low and the soundest way to raise the revenues in the long run is to cut the rates now." Both Presidents Ronald Reagan and George W. Bush made similar arguments, and the tax rate cuts had the effect of stimulating economic growth while increasing federal tax revenue and shifting a greater percentage of the tax burden on to wealthier individuals.
One very insightful part of Sowell's paper is the discussion about what Mellon called the "gesture of taxing the rich" -- namely, tax-exempt securities that he tried unsuccessfully to put an end to. Tax-exempt securities and other tax breaks are valuable tools in the politics of class warfare and envy. Politicians have it both ways. They get votes by raising taxes on the wealthy -- or threatening to do so -- and at the same time provide the wealthy with a way out of high taxes through tax-exempt securities. This explains how President Obama can raise tens of millions of dollars in campaign contributions from Hollywood millionaires and Wall Street's rich and powerful. "Tax cuts for the rich" demagoguery is simply the height of deceit perpetrated on the gullible people and useful idiots.
You can bet that the White House has people reading every bit of the news, including this column and Dr. Sowell's article. You can bet some people in the news media will read it, as well. Despite the facts that Sowell has marshaled, they will continue to use trickle down theory and "tax cuts for the rich" demagoguery, even though they now have hard evidence to the contrary, because they can count on widespread gullibility and inability to do critical thinking.
