In the 30s, one of the reasons European Socialists rejected the Moscow model (violent overthrow coordinated by Moscow) in favor of Republican Socialism (working within existing Constitutional constructs to achieve revolution) is because they deemed all major industrial economies to be sufficiently Socialist already.
Thus we know for the Bolshevik, Socialist, liberal, progressivist, Communist, etc., etc., there is no such thing as enough, complete, or sufficiently. The mantra is More! until the result is North Korea, Cuba, or Venezuela.
