A fundamental point of departure for Marxism in the US today is that the capitalist system is regressing to the state of inequality that existed around the turn of the century. Statistics bear this out, as for example those cited by Andrew Hacker in his book "Money".
A socialist explanation for this phenomenon is quite elegant and simple. Money is being taken out of the pockets of the working class and put into the bank accounts of the ruling class. The redress would be to put a taxation of one hundred percent on all incomes over a million dollars or something like that. The call for tax redistribution can be used as a means to raise socialist themes. Socialism, you remember what that was, don't you, Jim?
