He's actually not that rich... All image and pretense
He's to a certainty not as rich as Putin. That doesn't mean he isn't rich compared to most other people, even after acknowledging his debts.
Did Trump build that while ruling a country and calling those earning $300 a month middle class?
Well Trump certainly used his position to enrich the Trump organization. But in a much more blatantly open manner. Putin is probably the single richest person on Earth, pretending to be one of the people and living off the official presidential salary of about 130000 USD.
Putin is a lot richer and more intelligent than Trump. I genuinely think that's why he adores him.
