-Oh, but the right kind of organizer could just slap people around a -bunch and shout "Shed your petit bourgeois illusions! You're working -class!!" A noble discontent (no relation to noble rot, right?) would -quickly set in.
Although very interesting studies -- and the experience of union political organizers -- has shown that if you talk to people at the workplace, they are much more receptive to thinking of themselves as working class and viewing issues in that prism. Unions have found that they get far higher union member support for endorsed candidates when they contact them at work than if they contact them at home.
So identity if very situational, in the physical sense of the word.
