What does modern society primarily spend its entertainment dollar on? Everything that is immoral. Trying to teach children morality is based upon the expression "do as I say, not as I do."
Why should any kid swallow this? They see that immorality is attractive. They follow the adults and don't want to fall for some con job. Morality is indoctrination and if society is not indoctrinated, how are the young supposed to be taught what society rejects? Since we are as we are, everything is as it is including the collective support of immorality.
When a society is participating in and defending its loss of quality and has no idea how to change the present, why would you expect the young to not want to join the party and glorify sex, drugs, and rock and roll as it descends into forced statist slavery?"The future is made of the same stuff as the present."
