Trump is not remotely worth billions. Best estimates are in the low 100 millions.
To the extent he has money, it’s from fleecing investors.
But assuming (for argument’s sake) his claimed net worth of $4 billion is real, he’s done a piss-poor job.
If he had simply put his $400,000,000 inheritance in an indexed mutual fund he’d have way more money than even his current fanciful claims — $13 billion, specifically.

And of course, that’s the barest level of performance.
Other billionaires’ net worths have beaten the stock market’s growth in that time. Bill Gates, for example, saw his grow increase 7,173% since 1988 to $80 billion. Warren Buffet’s wealth grew 2,612% in the same time period, to $67.8 billion.
The idea that Trump is somehow not good in business is so laughable; but such ignorance must be the basis of support for career politicians with no business background, like Cruz, Rubio etc.
I am giving the benefit of the doubt, here, that the issue is ignorance and not actual malice like Obama.
