Try to pay attention. I'm not arguing against an increasing marginal tax system.

I'm arguing that tax revenue should not grow with income level, they should grow with population [1]. Crime is a part of society, but increasing income levels do not increase crime or increase the cost of road repairs.

Take your favorite progressive tax system. Multiply all tax rates by 1/2. Your new tax system is just as progressive as the old one.

[1] That's my leading order argument. As a second order correction, poor people tend to cost more money than rich people.
