Ask people who aren't your parents or grandparents how wonderful the 1980s were... try someone poor and black as a jumping off point.
There was as much promiscuity, drug use, alcoholism, etc etc in the wonderful 1950s - but it was just covered up.
Yeah this idyllic image of the 1950's and the 1980's makes me lol sometimes.
Especially this whole "moral 1950's" argument. I mean really. The 1950's probably had looser morals than the 1920s. And a lot of people got high during the fifties, you just don't hear about it as often. Why? Because people were popping pills and not blowing Mary Jane that's why.
EDIT: Wait a minute, actually people were smoking Mary Jane. The idiot media just doesn't want you to know that it's always been cool!
