Don't know about him, but the example I try to plant in people's minds is that early in his presidency, he wanted money for a wall, democrats wanted "dreamers" to get citizenship (and every state has infrastructure projects they want). Seemed like great deal making ground to me. I was prepared at the time to be wrong about him and waited to see anything come out along the lines of a bargain. But he proved unable to do it.
A billionaire took the family fortune of billions and reduced it to mere millions over several decades.
It is astonishing how difficult it is for a billion USD to get spent on luxury items would still remain in the hundreds of millions for decades. A billionaire has to leech off the workers and wages and company and society to amass a billion dollars. It is greed on a different scope and scale.
Anyone who hits a billion dollars should get instant prison time. A single island in the middle of nowhere with ALL amenities. Jetski, Yatch, Resort, everything EXCEPT coming back into normal society. NO visitors, NO people. Just prison guards and maintenance staff once a month under supervision and then everyone leaves under surveillance.
And I don't think we will have to worry about running out of islands ... there are more abandoned rocks in the middle of the oceans than there are billionaires on the planet.
Go back and look at his history, even before he got into politics.
He has always had exactly one tactic. Use his near-infinite resources to delay things indefinitely until the other side either gives into his demands or simply runs out of resources to keep fighting. Of everything he has ever been involved in, I don't think he's ever actually won a single thing on the merits. And when that doesn't work?
He caves. He always caves. His opponents walk away with everything they want while he gets nothing, and then still goes out to the press and tells everybody what a shrewd negotiator he is. The same thing happens every time he sits on the other side of a negotiating table and couldn't either bully or delay his way out of it. His entire negotiating skillset is to hide behind an army of lawyers until the other side runs out of money. He banks on the fact that very, very few people (or even businesses for that matter) have the resources needed to outlast him and force him to the negotiating table in the first place, because he has no clue what to do when he gets there.
The man is pathetically stupid to a point I did not think was achievable by human beings. Give me an hour, a deck of cards, and a poker table with him and I'd be able to own everything that man has, and I'd be able to do it with nothing more than a jack of diamonds and a Forest card from Magic: The Gathering. He was just born on top of a pile of money that most human beings couldn't burn through even if they tried, and Trump took that as a personal challenge.
