...”successful in business”....
Well not really in the respect of “how” he’s become wealthy. The IRS audits him every year because of his corrupt tactics they are all too familiar with.....same with banks who deal very hesitantly with him.
Trumps answer when his real estate business ventures failed was to change direction and simply sell the use of his brand name on buildings others actually own, not him...... Also gaining partners, (he often screwed), to invest with him because he couldn’t do it himself....He also swung into TV with his shows and working the entertainment circuit ....and while doing so sell clothing, wine etc....but always with the help of investors.
Not to mention he’s a master at money funneling to his own projects.....open a fund raiser etc. which will always go directly to rump, use it also to funnel until the complaints come that the money isn’t going where it’s suppose to then he coughs it up.
Only one third of the money Trump raised at his big Veteran rally has gone to the vets.
