Why not? He inherited a rumored to be $200M, decades earlier, and by 90', he was a billionaire who filed bankruptcy and, according to the Guiness Book of Records, the quickest to make it back. I did the same example, months ago, using 75', so 40yrs., and investing in the SPY. He would have been worth $11B, and $27B(with dividends reinvested), respectively. His rate of return, was something like 3-4%, per year, to be worth a few billion(according to Forbes). He has a dozen failed business in the last few years including everything from water and vodka to his scam Trump University. I think the only other billionaire as dangerous to investors is George Economou, who uses Dryships, as his own personal piggy bank on its way to bankruptcy while his private company makes a fortune.lol
