Class warfare is a republican talking point, and has been for years. Always to indicate that the middle and lower classes are trying to wage ware against the rich, to get more of the economic pie.
liberals want to divide and conquer with class war just as Marx described. Its not surprising that our liberals spied for Stalin and gave him the bomb. Marx taught that the rich, in effect, steal from the lower classes while conservative intellectuals know that the pie expands for all in the absence if liberal programs that attack the middle and lower classes such as:
1) Great Society near -genocide against, primarily, blacks
2) allowing 20 million illegal workers
3) union and tax policy that ships millions of jobs off-shore
4) socialist health care that is 5 times more costly than capitalism would be
