That is not an absolute statement that it would be like that, and you make it sound like the rich would get taxed to death.... that will never happen.BUt if you overtax the producers where is the incentive to work? If my slacker neighbour refuses to work more than 40 hrs a week and takes home $40000 after taxes and I put in 60 or so hrs only to be taxed down to the same takehome why would I bother to try to get ahead?
Topics like this always get pushed to extreme examples and hypothetical set ups.
At the end of the day the wealthy have way more oppertunities to avoid paying thier share.
