From Thomas Sowell at National Review, What Democrats Mean by ‘Paying Your Fair Share’
Whether in politics or in the media, words are increasingly used, not to convey facts or even allegations of facts, but simply to arouse emotions. Undefined words are a big handicap in logic, but they are a big plus in politics, where the goal is not clarity but victory — and the votes of gullible people count just as much as the votes of people who have common sense.
When the state of Maryland raised its tax rate on people with incomes of a million dollars a year or more, the number of such people living in Maryland fell from nearly 8,000 to fewer than 6,000. Although it had been projected that the tax revenue collected from such people in Maryland would rise by $106 million, instead these revenues FELL by $257 million.
Conversely, there have been some reductions in high tax rates that brought in more tax revenues at the lower rates. This happened as far back as the Coolidge administration in the 1920s. It also happened in the Kennedy administration in the 1960s, the Reagan administration in the 1980s, and most recently in the Bush 43 administration. There was a similar reaction in Iceland.
There is nothing inevitable about either a higher or a lower amount of tax revenues, whether the tax rate is raised or lowered. The government can only set tax rates. How that will affect the tax revenues actually received depends on how people react, and you can know that only after the fact. Sophisticated projections have often been laughably wrong.
Contrary to the way some people on the left conceive of the world, neither rich people nor poor people are inert blocks of wood, to be moved about like pieces on a chess board, to carry out some grand design from on high.
