The marxist definition of class is useful to the above discussion.Marx basically argued that a person's class was determined by his/her relationship to the means of production.Some people are virulently dismissive of class as a concept but try getting into Eton or Fettes College without paying the huge fees and you will class conflict in action.

The premise of many seems to be that if you are working class you must be a cultureless clod but surely the great songs collected by Cecil Sharpe came from the rural working class in the main and a load of others came from the industrial working class.Also much of the driving force in popular music has come from the most disenfranchised members of the working class and I am thinking of the blues,gypsy music and rocknroll.
