Am I making this up?
What media can safely say 71% of the audience is over 21? A scary movie? Something with explicit sex, what, because that is what teens will run and watch.
Federal and local courts went head to head about alcohol advertising in the 90s and targeting teens (or under aged drinkers 21 in the US since early 1980s). Remember Coors nearly going bankrupt, or Camel being attacked because of their camel cartoon character ads? Superficial hypocritical measures that only lawyers and insurance companies can appreciate.
The division between beer and malt-liquor/liquor in the US is very specific to US regulation that separates beer from liquor. From state to state to sell liquor beer and wine may be separate licenses.
Did any of this have an impact in reducing under 21 addiction, mortality, DUI rates? NO!!
The vast majority of homeless in the US historically has been women with children (not and but with) who were not substance abusers. The image of being homeless because of substance abuse was right-wing/neo-liberal propaganda to shift blame to the victims. And just like their spiritual father Goebels said, throw mud and some of it will stick (for generations I might add). The way the image was reinforced was because sub.abusers were more visible, declining shelters when available, or safer out of site places. So people actually saw what they were told. When you see a woman with a cart full of stuff and a kid or two following her on the street you don't identify her as homeless, the sub.abuser laying down in a carton box you do.
