As usual, Lixy leaves out useful information. A few items:
The growth in total incomes was concentrated among those making more than $1 million. The number of such taxpayers grew by more than 26 percent, to 303,817 in 2005, from 239,685 in 2000.
The I.R.S. data showed that the number of Americans making less than $25,000 a year shrank, down by 3.2 million, or 5.5 percent.
The number of taxpayers making more than $100,000 grew by nearly 3.4 million and accounted for more than two-thirds of the growth in the number of returns filed in 2005 compared with those in 2000.
And, of course, mathematically, any broad-based tax cut that affects all brackets will generate more tax savings on the whole for the upper paying brackets, for the exact same reason they pay more into the system than lower brackets - a percentage of a larger number is bigger than the exact same percentage of a smaller number.
