Shifting Sands of Marxism -- Book

Where do these tenets of Marx's views stand among the Marxists and the broader left today? It is barely a lip service to the prophet. In maintaining Marx's "materialist" view his disciples are hardly any different from the Christians and Moslems who have tried to decipher the principles of mathematics and physics from the pages of Bible and Qur'an, and with every new scientific advancement they belabor to justify their holy books.

Exploitation -- Book

Marx's notion of class begins with the assumption that there was a stage not too long ago when there were no classes, i.e. there were no privileges and no exploitation. He contends that in the primitive tribes everyone was equal because everyone more or less did the same thing, everyone consumed the same and at the end of the day there was nothing left. There was no accumulation of things and therefore no basis for privilege and therefore no "classes".
