Personally, I don't care what the drinking age is, just as long as if and when the person is arrested for drunken driving or hurting/killing someone while doing it steps up to the plate and says, "Yes, out of my stupidity and selfishness, I did this crime. I don't deserve a plea bargain. I am guilty, no question about it."
We, in the United States, have way too many drunks that don't take responsibility for anything and are quick to blame anyone and everyone else for their actions. We have way too many "programs" to "help" people quit drinking. They work as effectively as the chances are for me to become pregnant.
I favor a permanent ban to driving "PRIVILEGES" to anyone and everyone driving, caught and convicted. Automatic death penalty to those who kill or severly disable someone because of their drunkenness. No appeals.
