I explained what I think about the two-tier tax system in a follow up comment below. I agree that what happened to Trump's boy is an abuse of power- because of two-tier application of law, as well as the two-tier tax code.

What annoys me about what Trump is griping about, is that his complaint appears more centered on the idea that his boy didn't get special exclusion for his crime- like everyone else in "the big club" always does, rather than denouncing the whole corrupt system that routinely allows white collar crimes to go unpunished, nor does he condemn the entirety of asinine tax laws. That bothers me.
