Marxism's Abject Failure Was Inevitable.

Dahrendorf's analysis of Marxism explained why the developments did not lead to the revolution of the proletariat. In his book Class and Class Conflict in Industrial Society Dahrendorf's deems that things changed since Marx wrote his book at 7 directions in a way that make Marxist theory of class inapplicable. These changes are: 1- The capitalist class decomposition; 2- The labour class decomposition; 3- The New Middle Class Composition; 4- Social mobility; 5- The promotion of legal and political equality; 6- The Institutionalization of class conflict; 7- the moral and cultural changes in the Capitalist society that makes it different from a mere industrial society.
This is fairly sound thinking. So when each of these seven was ignored by blinkered 'socialists' - conflict and decay were inevitable. Point 4 is the real key to it all, it would seem to me.
(So why did socialists and their fellow travellers destroy the grammar schools, I ask myself?)
