The issue of tax burden is that the only loser are the people. Government issues taxes and can enforce it violently, so Government is the only winner in the tax game. For the wealthy, the move to a FairTax is neutral they don't benefit from it just as they don't have the same negative effects that a progressive system has with its loopholes. Also, we need to stop thinking that our economy will get better if we somehow increase the tax burden on the rich. What we need to start thinking is how to improve the plight of the poor and the needy.
The reason why I supported the FairTax because of the prebate and it increases the purchasing power of the poor. When the poor can keep 100% of their pay, they control what they can spend on. For the middle class, the same deal: we can have families improve their lives, save up for college, be masters of their spending, and pave the way for more charity. The rich will continue being rich, regardless but if we can ease the tax burden on the middle class and the poor by removing income taxes it'd be a big break.
