True. But Trump owned his casinos during a time when the only real competition on the east coast was the mob and a few Indian casinos. From what all the experts say about his failures, the properties carried too much debt (he leveraged the shit out of them to make them fancy...) and very badly managed. I can sort of forgive the first part, because I get the idea that to compete with Vegas, you might need to make the place extravagant and a destination. But, like many of Trump's businesses, they were very poorly managed. Which brings into question Trump's declaration that he's a smart businessman or a great deal maker. Yes, he has a ghostwritten book called the Art of the Deal...but the writer says Trump didn't really contribute much except for some "deal" principles that he needed to flesh out to make any sense...
And, even ignoring the casino's, he has a MASSIVE string of failed business ventures, from Trump Steaks and Trump Shuttle to Trump Mortgage and Trump University (which, interestingly, was being investigated for fraud in Florida, but the AG dropped the investigation shortly after the Trump Foundation made a $25,000 donation to her PAC ....and that AG was none other than current Attorney General Pam Bondi...and that donation was fined for being an illegal contribution because it came from a charity). Many of these ventures were poorly timed, like Trump Mortgages, which launched in 2006, a year before the subprime mortgages started to default...or his interference in things like USFL and the New Jersey Generals. There is a saying, and it still holds fairly true, that Everything Trump Touches Dies.
