Plenty is doing.
"[Early socialists] were uplifted by tremendous hopes of ideal societies just round the corner. They delighted in thoughts of communes and Owenite towns; and later of model co-operatives, kibbutzim, public ownership, national investment boards, ideal council housing, 'waving cornfields and ballet in the evening'. All that has now vanished, with the discrediting alike of Soviet and Chinese communism on the one hand and of social democratic nationalisation on the other. No one now believes in these utopias, and communal experiments are at best a minority taste. So all that remains is the discontent with existing society, which has filled the vacuum left by the collapse of idealistic solutions and now dominates the minds of the middle-class Left almost to the exclusion of anything else. They have developed a positive taste for misery-mongering and expect the rest of us to share it."
