What really helped Donald Trump, in my opinion, was a clear understanding that those whom he rallied against, were clueless, as well as utterly corrupt, and dangerous in their pretensions & associations; that understanding, coupled with a John Wayne like contempt for bullies, motivated him into stepping into the breach, to defend and restore the heritage that almost all Americans once honored.
It was clear insight and a moral compass--even more than personal wealth--which powered Donald Trump's valorous effort.
