This meme isn’t saying Socialism will not prevail. Rather, it’s saying that even though Socialists can’t individually beat Capitalism right now, as Capitalism decays Socialists increase in number and Capitalists weaken in strength, making Socialist victory more probable over time.

Beat or being able to flourish once the Goth Galadriel is gone?

Because historically the revolutionary forces (the one toppling the bourgeoisie) are extremely shitty governors (just continuing mass murdering & plundering which kinda makes sense if you think how & what they have been through).

In very few historical instances of regime changes all the previous actors as well as anyone involved in the revolution were prohibited in forming the new structure. This helps a lot to actually change the system.

You wouldn’t want to move from a czar to a dictator, thats long term the same bullshit, only makes things better in short term.

Same with any oligarchy, if it exists and has power than it matters little what kind of regime it technically is.
