The neat thing about Trump is you can't tell if he's trying to destroy America for himself or outside entities, if he thinks these are actually good ideas, if he genuinely has no idea how tariffs work, or if he's trying to get thrown out of office because he didn't want the job in the first place and he just wants to skip to the part where he can make a bunch of money once out of office.
Trump usually starts out doing things he doesn't know anything about because someone tells him that he can't (real estate, casino's, airlines, TV, campaigning for President, President).
He's quite a fast learner so at some point he 'gets it' at a basic level. But then he thinks he's better than anybody at what he's doing and all his bad decisions come back to haunt him later.
When the whole thing collapses he jumps out with a parachute safely landing on one of his golf courses or hotels. Leaving the venture in debt and bankrupt and the workers unpaid.
Except in this case the venture is the United States of America and the global economy.
