I know he inherited a business that is now worth less than the inheritance would be if it had just been in the bank this entire time (or at least based on projected net worth from Fortune, not his own inflated claims for which there is no substantiation since he refuses to release his tax records). I know this
Salon article claims he had lost 55 million $ (adjusted) before he was 33. I know he's had 4 big bankruptcies. I know he used campaign funds to pay his own businesses for campaigning. I know a great many people think the reason he refuses to release his tax returns is because they will show he has lied about how much money he has and that he's actually managed to squandered far more than he wants us to believe.
The one thing Trump is truly good at is bullshitting, and I personally believe he's managed to bullshit the American public into thinking he's a good business man based on the current result of his huge inheritence, and that it's one gigantic lie.
I know I have little substantiation for claiming all this about his net worth, but all you have is his worth, and as much as you guys talk about Hillary being a liar (which she obviously is), fact checkers show that the number of lies this guy told consistently far exceeded Hillary, so thinking he's a good business man is beyond naive. You've fallen for his bullshit then.
