Trump has largely not had that kind of money. He’s had a _lot_ of money, many many times more than most, but by all accounts except his own, those numbers are much lower than he likes to brag about. Well, they were - there’s been a troubling amount of money going out of the federal government that isn’t well-accounted for under his reign.
He had the kind of money that can hire expensive projects on trust that payment in full will be rendered, but only kept his money by often not paying out.
As with all things Trump, even up to the new ballroom not having a front door despite the massive staircase, his wealth is more in appearance, and less in actual assets…or was. Of course, someday maybe we will know the true extent or shortfall of his bank accounts
Don’t forget the fairly naked corruption around his crypto coins too…
He may not have been that successful as a businessman, but his whole clan are monetising the Whitehouse.
