If this tax regime was put in place, people would find other ways to shelter their money; I don't think the government would end up with a significant windfall.

If this tax regime was put in place, people would find other ways to shelter their money; I don't think the government would end up with a significant windfall. Maybe they'd invest in their company or start a new company and invest in that. I'm sure that with such a large income, they would have many places to put that money.
