From the Hegemony section:
..."This bloc(the hegemonic super-structure he refers to) forms the basis of consent to a certain social order, which produces and re-produces the hegemony of the dominant class through a nexus of institutions, social relations, and ideas. In this manner, Gramsci developed a theory that emphasized the importance of the political and ideological superstructure...
I hate to say this, but Gramsci was pretty sharp. His writings were analytical and general, but he was and remains the left's go-to guy for explaining the fact that nobody in the post-WWII West cares for communism. The ideal is that the "masses" did not understand their oppression because it surrounded them; somebody made the analogy of a fish in water, the fish has no conception of water though it's all around him.
I'm not sure Gramsci subscribed the strategy of infiltrating and subverting these "hegemonic institutions" from within, but it has become the left's preferred strategy--no truncheons or tear gas, a fine salary, and perks to boot. Besides, they figure the proletariat is dumb and doesn't care for these insights.
Note to all millionaires and billionaires: spend every penny of your money, and do not create some foundation or benevolent trust. They'll get it. Seriously though, we should study these guys--two can play the game.
