> Completely destroying the US is not ideal for him
How can you say? The ultra wealthy are not playing team sports. If the country burned tomorrow they would just sit on their yacht or buy citizenship somewhere else.
Sure the lion share of his investments are currently in the US, but that could easily change.
Most cynically? I sincerely believe there's more value he can extract from American workers if he can keep the ride going on just a bit longer. For example: it's better to keep the stock market a float a volatile so he can transfer a bit more wealth from the American people before it does eventually break down.
Yes, they'll all be on yachts when the shit hits the fan, but they're still fighting to figure out who get the biggest yacht, and right now it seems like Trump has more to milk from us before he entirely lets this thing fall apart.
