As Willie Sutton said, "Because that's where the money is."
Strange that people don't seem to make the connection that people pay a disproportionate amount of taxes, not because they get picked on, but because they make a disproportionate amount of money. Overall, a good problem to have.
Let 'er rip.
FWIW, that top 20% who pay 84% of the income tax only make 51% of the total income. You are right though, I would rather be rich in this country than poor.
