Wrong. Trump has been horrible in the business world. He's gone through inherited wealth ... had grandiose ideas... borrowed too much ... refused to pay too many people ... hired too many illegals... numerous bankruptcies hanging creditors out to dry ... record numbers of lawsuits ... started fraudulent money-making schemes as in Trump University, Trump wine, Trump beef... I could go on.
True enough. But Trump
has been very successful in marketing himself -- there's no way he could keep starting then running businesses into the ground without significant investors, and for whatever reason he's always been able to find them.
Trump is very effective at influencing peoples' perceptions of reality, as it applies to him and his enterprises -- whether they've been in business or in politics.
He does deal with reality; he just doesn't depend upon it.
