I think it'll be real interesting if "Communist" nations actually win.
They're way more unified and cohesive than capitalist ones.
North Korea is of course, a shithole, but so is south korea by many standards. At least North Koreans are unified, though. They can work together towards a common goal. Everyone in capitalist nations is just looking out for themselves and their wallets.
See how quickly the West folded when Ukraine started losing? North Korea didn't fold when Russia was having trouble.
As soon as the going gets tough, they scatter like roaches.
The reason DPRK is a "shithole" now is because the burger empire has been choking off their trade since USSR collapsed. The standard of living back in Soviet days war fairly high, and the economic growth there was solid. The very fact that DPRK managed to keep cohesion and make it through a hard period of sanctions shows that the system fundamentally works. Meanwhile, occupied Korea has no excuse for being a shithole.
