Yes like a said a true flat tax is proportional, I never said it was progressive. I'm for proportional taxation. The reason I don't like progressive taxation is because it incentives tax avoidance and tax law often becomes a 100 000 page quagmire that the extremely wealthy learn or hire someone to manipulate. I don't understand how a solution to a progressive tax system that doesn't work is more progressivism. Simplify and reduce the incentive for tax avoidance by using a proportional system.
