Indeed, I do remember the campaigns. That's not to say that everyone was driving their cars drunk all the time.
In most scenarios there is a small percentage of people ruining it for the others.
If everyone waited around for the government to lead them in everyday life, nothing would get done.
My parents have taught me a gazillion more things than any government possibly could.
Government can't teach compassion, affection, love, commitment, solace. Likewise they can't teach the opposites.
