At least during the Great Depression you had independent markets like the USSR. Good luck investing, though. :-) The point about the higher independence of markets still stands. Great Depression was named as such by Americans (just like World Series, etc), but wasn't as global as the name implies.
Nowadays the world's economy operates in even more globalized way and when the biggest players get hit, everyone suffers (1998, dotcom, 2008, covid). That's why the tariff war was such a counter-productive idea; even if you theoretically end up on top, everyone will still lose, including you.
