Talk to any Socialist and they have a crack-pot idea of the link between "goodness" and being middle class. They claim that because the middle-classes are the dominant- force in society, it is their idea of goodness and quality which is represented in the media, a media which is dominated by the middle-classes. They are therefore touting the middle class way of living as being good. So the Socialists claim that there is a bias here "people are judged to be good because they are middle-class"
This is nonsense of course. It is in fact the other way round: "people are middle-class because they are or have been good". They maintain or ascend to that particular class because they have not been selfish and hedonistic. Nor have they made poor choices. They have been prudent, patient and wise.
On the whole the middle classes deserve their rewards. They are decent and deserve a decent life.
