Vera Mukhina, THE sculptor behind the worker and kolkhoz woman sculpture, would’ve probably convinced people to keep it purely for artistic value. She allegedly did it with the “Freedom monument” in Latvia, but the Latvian “Freedom” statue is so ugly I wouldn’t have listened.

Even if a revolution happens in the US, that doesn’t mean the people as a whole are commited ideological socialists. They will largely be politically unaware but supportive of the new revolutionary government, however that doesn’t mean they won’t have any affection for old symbols.
