Again, you are asking me to support your arguments, I won't. I have countered your arguments, you cannot show anything to back your claims after repeated requests. Now you are asking the same questions of me that have already been answered, so why would my answering them again a second time do any good. You want me to go back, but here you are repeating what has already been debated. I know this game, it played on forums like this where comments get buried, where a poster can ask the same thing again and act as if it has not been covered.
I already showed how it causes increased inequality, you won't back your claim that a flat tax decreases inequality in wealth. You have not shown it in this thread, you have provided nothing to back your claim.
Beyond this, you are totally wrong on the effect of a flat 30% on middle earners. It doubles their tax rate. It is worse for lower income earners, it triples their tax rate. This proves without my showing you documentation that it makes wealth inequality greater.
