How do the tariffs benefit Trump?

[Ocelot II]

9. Trump is short-sighted, stupid, and frequently irrational and prone to magical thinking.

Of course he and his family and his minions can benefit financially in the short term by shorting the market, but that won't hold up in the long term if there's a global recession. Trump probably really thinks tariffs are a money-maker that will offset huge tax cuts and everything will be peachy and he will be admired by everyone. And it really, really tickles his willie that he's able to inflict economic pain on other countries that have refused to knuckle under to his demands. Denmark won't sell Greenland? OK, I'll screw the entire EU with crushing tariffs. Canada doesn't want to become the 51st state? OK, big tariffs for you! Fuck all you little countries, I win!
