Whether inherited or produced by upbringing, perhaps it was Trumpf's way of surviving his father, like his brother didn't. I'll have to read the book.
On a side note, the facial resemblance between Mary and Donald is too similar, like if he was a cross dresser.

My takeaway is that her father (Trump’s brother) wasn’t interested in the family business and just wanted to be a pilot. Trump Snr didn’t approve and young Donny did nothing to help matters, even going so far as to try and disinherit his brother.
