I think i figured out why Trump is so keen on eliminating taxes on "tips"
The US Supreme Court ruled it was legal to give politicians gifts for policy decisions, even if you benefit from the decision,, as long as you do so after the fact. A tip, if you will.
But politicians who accept "tips" still have to declare them on tax forms. For example, tax crimes are the most likely path to impeaching Clarence Thomas.
No joke, I think that's what's going on here
