progressive taxes are communistic and laid out by marx in the manifesto, so are flat rate taxes. if i had to chose any i would go with a flat fee.
That would absolutely bankrupt the government. To get enough money to come anywhere even remotely close to their current budget, to get remotely close to even half or maybe even a quarter of the current budget, the flat fee would have to be so high that most Americans couldn’t pay it. Collection efforts would cost a fortune and put a huge segment of our population out on the street, and before long we’d see rioting and outright revolution.
