<p>In colleges the drinking age is really such a fantasy that the above would have little effect besides perhaps making it more out in the open (it would be nice to buy alcohol myself at a bar instead of asking my senior friend to do it?). Quite a few bars operate on the principle that if you have the money, they have the drinks, as is.</p>
<p>Honestly I think people need to give up on fully preventing underage drinking, as you’re simply not going to succeed. You can repeat how it’s illegal, how it mustn’t be tolerated, etc., but you might as well bang your head against the wall. If your teenager wants to drink, he/she will find a way. The drinking age being raised to 21 reduces the supply of people who are willing to buy alcohol for teens but it certainly doesn’t eliminate it.</p>
<p>Are there teens who don’t drink? Certainly. At least in my school though, the majority did. And setting a curfew at 11PM or not letting your kid go to a party where you don’t know the parents won’t change anything. We can drink at 8PM just as easily and say we’re going to see a movie with friends.</p>
