Gee golly, aren't WE high and mighty. Defending the blue collar, Plane? They don't need defending. We all have roles to play, white collar, pink collar and blue collar. Everyone is called to be one and/or the other. Society needs all these "types" to be effective.
All this is really nice DISCUSSION, but ask many parents whether they would like their capable children to have a white collar job or a blue collar one and see what the response is.
