Let's be fair to about this. Trump didn't actually do anything here himself except sell out his name, likeness, endorsements, money, and lawyers to it (and continues to as he defends it against lawsuits from students and several State investigations).
I doubt he wrote the curriculum or lack thereof or oversaw day to day operations or structure.
He is for sale, he always has been and he'll put his name on anything for the right price. He doesn't have the personal value structure to say if something is right or wrong and stand by that. He just goes to wherever gives the biggest paychecks.
Just like the diet pill scam with his name on it. I doubt he had a thing to do with the formula of the pills. Someone just came to him with a very big check asking him to put his name on it and he didn't care it was a multi-level pyramid scheme, he was selling out his name and endorsement.
Just like Trump water, Trump vodka, Trump monopoly, Trump clothing, Trump chocolate, Trump coffee, The Apprentice, the WWE.. and so on... he can't be responsible for all that, he just sells out his name and endorsement to whomever pays.
It is like blaming (or giving credit) to an actor for the roles they play.
That only begs the question, what does he really believe versus endorses because it gives him the 'payoff' he wants? Will he change that if the payoff goes another way?
