Guess what - many billionaires don't pay tax, especially property developers. This is only news to those ignorant of the tax laws or those who don't know how the big fish play the game with million dollar accountants. If you make a "loss" you don't pay.
Amazon for instance received a TAX REBATE in 2018 of 129 USD (2 100 ZAR) (2 100 ZAR) (2 100 ZAR) million. I suggest you watch the first half of this episode of Keiser Report to get a clue. The second half deals with "Hollywood Accounting".
Max and Stacy and their guest in 2016 said why Donald didn't want to release his tax returns. No Russia conspiracy like the leftist media claimed. Just "Hollywood Accounting" - google it if you don't know what that is, or watch the episode. The talking heads on TV don't know squat, or of they did they didn't say it.
