For the past decade, we have doubled down on this theory of supply side economics with the tax cuts sponsored by President George W. Bush in 2001 and 2003, which President Obama has agreed to continue for two years.
Tax policy is something the framers left to politics. And in politics, the facts often matter less then who has the biggest bullhorn.
The Mad Men who once ran campaigns featuring doctors extolling the health benefits of smoking are now busy marketing the dogma that tax cuts mean broad prosperity, no matter what the facts show.
As millions of Americans prepare to file their annual taxes, they do so in an environment of media-perpetuated tax myths. Here are a few points about taxes and the economy that you may not know, to consider as you prepare to file your taxes. (All figures are inflation adjusted.)
1. Poor Americans do pay taxes.Gretchen Carlson, the Fox News host, said last year "47 percent of Americans don't pay any taxes." John McCain and Sarah Palin both said similar things during the 2008 campaign about the bottom half of Americans.
Ari Fleischer, the former Bush White House spokesman, once said "50 percent of the country gets benefits without paying for them."
Actually, they pay lots of taxes-just not lots of federal income taxes.
Data from the Tax Foundation shows that in 2008, the average income for the bottom half of taxpayers was $15,300.
This year the first $9,350 of income is exempt from taxes for singles and $18,700 for married couples, just slightly more than in 2008. That means millions of the poor do not make enough to owe income taxes.
But they still pay plenty of other taxes, including federal payroll taxes. Between gas taxes, sales taxes, utility taxes, and other taxes, no one lives tax-free in America.
When it comes to state and local taxes, the poor bear a heavier burden than the rich in all 50 states, Citizens for Tax Justice calculated from official data. In Alabama, for example, the burden on the poor is more than twice that of the top 1 percent. The one-fifth of Alabama families making less than $13,000 pay almost 11 percent of their income in state and local taxes, compared with less than 4 percent for those who make $229,000 or more.
2. The wealthiest Americans don't carry the burden.This is one of those oft-used canards. Sen. Rand Paul, the tea party favorite from Kentucky, told David Letterman recently that "the wealthy do pay most of the taxes in this country."
The internet is awash with statements that the top 1 percent pays, depending on the year, 38 percent or more than 40 percent of taxes.
It's true that the top 1 percent of wage earners paid 38 percent of the federal income taxes in 2008 (the most recent year for which data is available). But people forget that the income tax is less than half of federal taxes and only one-fifth of taxes at all levels of government.
Social Security, Medicare, and unemployment insurance taxes (known as payroll taxes) are paid mostly by the bottom 90 percent of wage earners. That's because, once you reach $106,800 of income, you pay no more for Social Security, though the much smaller Medicare tax applies to all wages. Warren Buffett pays the exact same amount of Social Security taxes as someone who earns $106,800.
3. In fact, the wealthy are paying less taxes.The Internal Revenue Service issues an annual report on the 400 highest income-tax payers. In 1961, there were 398 taxpayers who made $1 million or more, so I compared their income tax burdens from that year to 2007.
Despite skyrocketing incomes, the federal tax burden on the richest 400 has been slashed, thanks for a variety of loopholes, allowable deductions, and other tools. The actual share of their income paid in taxes, according to the IRS, is 16.6 percent. Adding payroll taxes barely nudges that number.
