Class is an outdated and derogatory means of classifying people, we are all the same.
The only people I know who are working class are those who proudly tell me they are.
Usually these working class warriors have university degrees, and a socialist mentality, but their income and life style is far removed from their self description.
To put a class label on someone is to either admit you think they are better than you. Or; perish the thought, lower down the social scale than you.
It's a passé classification, and should be abolished.
