“... economists recognize that, other things equal, cuts in tax rates reduce tax revenues in percentage terms by less than the tax-rate reductions. Similarly, tax-rate increases do not raise tax revenues by as much in percentage terms as the tax-rate increases. This is true because changes in marginal tax rates alter taxpayer behavior and thus affect taxable income.”

“The joint committee invited economists of many economic stripes to model what would happen if America switched from the current code to a unified income tax or a consumption tax. Every economist who modeled reported that the consumption tax would increase long-term economic growth.”

“The most overwhelming proof that tax incentives have a relatively minor effect on individual charity is the tremendous consistency over time of giving as a percentage of income. Although the tax code has changed frequently and dramatically over the past twenty-three years, giving as a share of personal income has hovered around 1.83 percent. This measure reached as high as 1.95 percent in 1989 and as low as 1.71 percent in 1985. The narrow range has persisted even though the top marginal tax rate has fluctuated in that period from between 28 and 70 percent.”

“the larger the percentage of the national income taken by taxes the greater the deterrent to private production and employment. When the total tax burden grows beyond a bearable size, the problem of devising taxes that will not discourage and disrupt production becomes insoluble.”

“I will cut taxes - cut taxes - for 95 percent of all working families, because, in an economy like this, the last thing we should do is raise taxes on the middle class.”

“History lesson, folks: The tax system we have today—the one we've come to know and love—began ninety-four years ago as a (drum roll, please) flat tax! The monstrosity you see today is a flat tax on income after nearly a century of very imperfect evolution. At first, only a very small percentage of Americans were asked to pay income tax. In fact, that’s how they sold it to us—as a tax on the rich! Well, that all changed with World War II. The cost of the war effort led to an expansion of those who paid federal income taxes—and we were off to the races. The tax code was flattened again, if you will, in 1986. Since that time it has been amended 16,000 times. We now have more than 67,000 pages of statutes and regulations—which helps explain why, last year, nearly two-thirds of all tax filers had to seek professional help with their tax return.”
