As another friend, Rick Atkinison, writes in his background to the work:
The over-arching point of Mr. Clark’s critique was that the petty bourgeois intelligentsia, whether advocating for imperialism or socialism and regardless of the social structure within which they live, could only continue to exist as part of a parasitical strata. It is “parasitical” because in order to be “free” to pursue interesting ideas, conduct “principled” debate, research, write, etc. the intelligentsia must be supplied with the means of subsistence without “having to actually work for a living” (Ibid.). The essence of petty bourgeois ideological work, whether capitalist or socialist, then, is simply to define and proselytize “how the privileged status of their kind is to be secured.”
Tom writes in his Conclusion presented below:
If the working class is to go beyond this historical stage, it must reclaim the leadership of its own movement, and oppose the theory and practical program of the socialist intelligentsia with its own. While it may be a matter of speculation as to whether this will actually come about, there is no doubt that middle class intellectuals themselves will do everything in their power to postpone it. Marxism-Leninism is, after all, the last of the truly great religions, and if its influence in the working class dies, the last hope of the middle class dies with it.
