Check out Marcuse's 1969 "Essay on Liberation":
"By virtue of its basic position in the production process, by virtue of its numerical weight and the weight of exploitation, the working class is still the historical agent of revolution; by virtue of its sharing the stabilizing needs of the system, it has become a conservative, even counterrevolutionary force. [...] In the advanced capitalist countries, the radicalization of the working classes is counteracted by a socially engineered arrest of consciousness, and by the development and satisfaction of needs which perpetuate the servitude of the exploited. A vested interest in the existing system is thus fostered in the instinctual structure of the exploited, and the rupture with the continuum of repression - a necessary precondition of liberation - does not occur."

i like to think of the economic trifecta as a triangle.

People often tend to conflate communism and socialism down into one plane, but i don't think they're similar enough, socialism is more inverse to communism than anything. It's also more closely related to capitalism than communism (the modern western conceptualization of socialism at least)

to put it bluntly, communism is a subset of socialism.
