The Problem with a flat tax is that it is a consumer tax. When market fluctuates and consumerism falls, it automatically costs the government. Less jobs, less earners, less taxes, less government revenue. Also, when the government needs to operate above it's revenue stream I agree it will cause the government to increase the levels and thus, taxation above the promise. Progressive tax works but distribution of the levels needs to address progressively, and not layered like a cake. But that means that it has to be lowered to reach the levels of those who are currently not paying...And hence, not fair. And no, do not pay taxes on election day...Then it's too late.....Taxes should be an honor to pay, not a burden......
