Should mcdonalds have to change their menu items and advertising stratgies?

america is becoming fatter and lazier every day and they are always looking for a scapegoat. recently mcdonalds and other fast food resturaunts have been taking a lot of abuse from activists for serving unhealthy food and advertising to kids. critics say they are making america and its youth fat. is it really mcdonalds fault or is it the fault of the parents who let them eat there too much. i was watching a show on cnbc about this. they interviewed one mother who said her son loves mcdonalds and when he wants screams until she takes him. to me this sounds like a discipline issue but she blames it on advertising, what are your thoughts?
