Trump didn't get rich by settling up with everyone he's ripped off.
I confess I don’t know enough about Mr. Trump’s business history to comment in any meaningful manner on whether he’s ‘ripped off’ any other people, or how, when, etc.
I can only add that .... whatever other biz deals Trump’s had..... the TRUMP U thing LOOKS (at least) really bad...maybe because it was largely “average little folk” that lost out on the deal? Something like that, ...
So, I still think it would enhance Mr. Trump’s public image if he could settle with the TRUMP U folks.
