By what metric is he an extremely succesful businessman ? Why would he have to listen to experts to become president ? I personally think he's an expert salesman... But take away the wealth and time he was born in and he's neither president nor nearly as rich (he'd be comfortably off <> salesman. The truth is not always, but definitely very often, in the middle. I think most people don't like that answer.
