Based on this discussion, it looks like Trump is not a billionaire because he is a good at dealmaking. He had multiple ways to become a billionaire (investing in index funds, investing in gold, dealmaking, inventing Facebook).
Given the way he has chosen he wouldn't be a billionaire if he was bad at dealmaking. It's a relevant skill for winning political fights.
If you think that Trump just blabbers around what's on his mind, you are massively misreading the situation.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
