I'm not sure which country you guys who are saying "why don't the millionaires just pay the IRS more" are living in, but in the country I live in, when you pay more taxes than you owe, the IRS sends that money back to you. Not that I have had that particular experience in quite a few years.

I imagine other countries might have something similar.
