Ehh, but the income bracket varies wildly and doesn't show any sort of relation between tax rates and amounts earned. The question is are people less likely to produce another dollar of income if that dollar is taxed higher. Another tricky thing with the tax brackets is that it only applies to income tax. Once you're making over a certain amount most of your money will come in other forms such as stocks and dividends.
