Sociologist Melvin Kohn found that working class parents are mainly concerned that their children stay out of trouble. For discipline, they tend to use physical punishment. Middle class parent s focus more on developing their childrens curiosity, self-expression, and self-control they try to reason with their children instead of physical punishment. Blue collar workers are ussualy told what to do. Since they expect their children's lives to be like theirs, they stress obedience. Middle-class parents, in contrast, have work that requires more intiative, and they socialize their children into the qualities they find valuable.
