Listen, I agree with the latter half of your post, but I'm going to challenge the bolded. Saying things are "shit" for him or "will be shit for him" unless he's the richest man in the world is a false measure that exists only to try and make your post seem accurate but it's not.
Donald Trump is a dumb motherfucker who was born rich, skated through his entire life failing at business, including a casino, declaring multiple bankruptcies, and his life has changed...pretty much never at all. He has maintained wealth and assets throughout, all the while stiffing contractors, attorneys, lendors, anyone who's done business with him. But he's ended up fine. When things have looked troublesome, he reinvented himself as a fucking gameshow host, which spit shined his brand once more, and he rode that shit into a succesful long shot bid to be president of the United States. Once president, he broke laws, embarassed himself and us, attemped to end democracy, and failed at a re-election.
He then managed to wiggle past multiple court cases and evade any kind of consequences for his actions, by, once again, being elected President. And now he's been "given a mandate" to do whatever he wants, to demolish democracy, and a time in his life where he'll never be held accountable for any of it. The only thing likely to make him accountable is the same accountability we will all face: death. Because you're right, nothing lasts forever.
The worst pain this man has ever faced is bad headlines, embarassment, some bad press, but his raging narcissim brushes that aside and turns it into rage, and in no way alters his behavior in any way. And he's richer now thatn he's ever been, more powerful now than he's ever been, in a position to grift more money in the next few years than he did in the first 70 of his life, and is immune from prosecution. He controls armies.
But I guess you're right, things have been really shitty for this guy his whole life. He can spike the economy, but it won't hurt him. Just us.
P.S.: Shit on paper wealth all you want, but a vast majortiy of Elon Musk's wealth is paper, and yet he managed to buy himself a president with it.
