Why do you care how rich someone gets? How are people getting rich affecting you and your family? So let me see if I have this right, you make a 100000 and 20% in taxes=20,000 in taxes then because of incentive you grow that income to 200000 and your tax rates are 15% so you pay 30000 in taxes, because the tax rate drops from 20-15 that is a bad thing? that is liberal logic, not the fact that the govt. got 10000 more in taxes.
You really need to think a little more and feel a little less.
There's nothing surer. The rich get richer and the poor get poorer. In the meantime, in between time, ain't we got fun...
