Trump cares about two things and there is a huge variance between the two in importance.
1) His Legacy
This is more important to Trump than even money. This is what matters most. How his legacy is perceived, not just right now, but in his own "future world" mind. That's #1 for Trump and it's not close. If it was money first, he would have never gotten into the political game nor TV.
2) Money Now, don't get it wrong this is critical, but pales in comparison to what he perceives as his legacy. Nobody, no matter how rich is going to tarnish the perception of #1 no matter how much it brings to Trump's coffers.
Anyone that can not see how critical his Legacy is to Trump at this point hasn't been paying attention. Nobody is going to take away from that perception. Egomaniac out front should have told you.
For the record, neither of these is good. Being wrong or right either way isn't good for us. I just know Trump cares most about the history written about him. Being a billionaire isn't chump change either. So no, Trump isn't letting anyone, billionaire or not, tarnish his self perceived Legacy. He'd rather fight them and force them to bow then take their money, no ask for it. Based on past events, Leon will do anything to feel important. Feel, not be. Trump knows a fucking mark when he sees one. Leon is a mark and needs Trump more than Trump needs Leon. Even if it weren't true, "Fuck you Leon, bitch boi nerd, I'm the king and you're my bitch."
