Capitalism hasn’t even survived with stability in the short term: it’s yet to manage even a century without a catastrophic crisis.

Capitalism is dominant because it is the only model known to survive with stability long term over massive populations.

Gee I wonder why socialist countries you are thinking of just up and failed?! Just spontaneously happened, no external interference whatsoever, no siree!

They didn’t have to recede to survive, they were fucking killed that’s why they’re not socialist anymore. Because they were all overthrown or sanctioned to hell or invaded.
