Even that, he managed to fuck up. I believe Trump inherited 400 million decades ago and his current net worth after debts is supposedly close to 200-400 million. However he supposedly made a lot of money off the presidency, so he may be an actual billionaire now. But he wasted his inheritance. Also in the book written by his niece, his niece mentions how Donald sold the Fred Trump real estate empire at a loss because he needed money to pay off his creditors. I forget the exact figures, but I think Trump sold it at 1.3 billion and it was valued at 1.6 or more. its probably worth 5-10 billion now due to gentrification and real estate costs going up in NYC. Either way, stories of Donald being an idiot at business abound.
Charles Koch, from what I know, actually is a highly talented businessman. No idea about the rest of the Koch family. I get the impression the entire Koch family coasts off the business achievements of Charles Koch and Fred Koch sr.
