Twenty years ago, they raised the age to 21 from 18 in New Jersey to lower the shockingly high rate of highway deaths among drunk teenagers. It worked. I don't think it's going back down to eighteen anytime soon.
I bought beer and liquor since I'm 14...even at that age, I looked very adult. Amazingly, the very first time I got carded was on my eighteenth birthday. I went into the liquor store where I had bought so many times before, and the guy asked to see my ID. I was like, what, are you kidding? I was able to buy anyway.
After I joined the Navy, it was 18 for beer, 21 for liquor in Virginia, that is, if I was off base. It was a happy day on my 21st birthday, I didn't have to worry anymore.
It's all attitudes...there are countries in Europe where, if you got caught drunk driving, you'd get put into an insane asylum. They figure you must be totally crazy to get behind a wheel drunk and endanger everyone else on the road. Here in America, it's machismo. "Hey, I can drive!"
Whether you think it's right or wrong, you have to understand that the lowering of the drinking age isn't gonna happen now, not with the prevailing moods in our society. And, with binge drinking the rage on college campuses and elsewhere, the politicians feel perfectly justified in keeping the status quo.
