"He's a businessman."
How to respond: Just because Trump is rich does not mean that he is a successful, ethical, or respectable businessman — he recently settled a $25 million fraud lawsuit surrounding his Trump University. Trump has also still not released his tax returns, and the New York Times reported that it's possible Trump has evaded paying taxes for almost 20 years.
There is also ample evidence that Trump's business acumen is less-than-stellar. In fact, his track record includes inflating his net worth by more than $2.7 billion, borrowing $7.5 million from his father to pay back Chase for a defaulted loan, and failing to turn a profit on a series of ill-advised business ventures in sectors he knew nothing about. There is extensive documentation that he has botched multiple multimillion-dollar deals, lived off his father, and cheated hardworking people over the course of his career.
