The New York Times has been looking into Donald Trump's past finances and come to the conclusion that he was a terrible businessman…and often when he did succeed, it was with deals where he got others to invest heavily, they lost big and he got out with a lot of their money.
I'm not sure any of this really matters. The people who don't like the guy couldn't have a lower opinion of him than they already do. The people who do like the guy won't let anything change their mind. When any evidence comes up that shows he's shady or incompetent, Trump or his minions just deny it as "fake, fake, fake" without explaining or offering proof that it's fake.
I am reminded of back when I was attending U.C.L.A., there was a lecture announced by an author who insisted the Holocaust was a myth. It never happened, Hitler and his mob never killed a single Jew…it was all a hoax. And this author was offering a cash prize — I think it was $10,000 which was a lotta money in those days — to anyone who could prove by rules he set down that the Holocaust was true. And what were his rules? They stated that you had to prove it without using "phony evidence." And what constituted "phony evidence?" Well, since the Holocaust had never happened, anything that indicated it had was "phony evidence."
