As much fun as it is to laugh at the fits of rage thrown by those that rooted for Romney to win, I think we should snap back to reality and try to predict what the next 4 years have in store.
Now in terms of taxes Obama has promised during this campaign to increase taxes on the rich and close loopholes in a way their effective tax rate would no longer be lower than those making less money than them. I know that usually higher taxes lead to shifting money to foreign banks, but that might not happen due to the loophole (I need the specifics on this one) closings. Also some of these loopholes do have upsides to them, such as charity deductibles, closing them might have some ramifications for those non-wealth that also benefit from these loopholes.
