In as barebones as I can make it, SBF disappeared money from the wealthy with no return of investment. Trump held office and was able to deregulate and reduce taxes for the wealthy allowing their wealth to accumulate.
The laws that lead to such actions being classified as they are, are a direct result of the the rich imposing their desires on the world. Trump is a vessel for that to happen for most of them, so he is tolerated, more or less.
The fact that Trump was able to commit the frauds in the first place and only get attention from the law just now is part of the wealthy's SOP
I didn't say he was an ideal vessel. He's just managed to somehow be cool(?)er than they are with the population, and they benefit still. I don't mean like some illuminati type BS, just a matter of happy coincidences, and a few convenient occasional suggestions I'd imagine. Oh, and money.
Besides, the amount he's defrauded is essentially chump change once you consider insurance and assets etc.
