Drinking age from 21 to 25??

I do not agree with Mr. Ebeling about changing the drinking age from 21 to 25. Although he provides one good valid argument as in why they should change the drinking age, I do not believe it is enough. The story he provided stating that young people are irresponsible does not, in my opinion make a good enough argument. Yes young people are irresponsible and immature, but at the same time at what age do people really mature or become responsible, at 25? No, everyone matures at a different age, some around their 20s others late 20s and some really never mature. So comparing maturity with a person's age is not a good enough reason to change the drinking age.
Even now with what the drinking age is, some people argue that they should change it to 18 because they believe if a person is considered an adult and is able to fight for their country at age 18, then they should be able to legally drink alcohol. In my opinion 21 is a good age for legal consumption of alcohol, because by this age one has already finish high school or receive their GED, and is attending college or working.
If there were more arguments having to deal with health issues, economic issues or even educational issues, then maybe changing the drinking age would not sound like a bad idea. But in reality no matter what the drinking age is whether it stays at 21 or goes up to 25, younger people are still going to find a way to get alcohol. The problem i see with raising the drinking age to 25 is the fact that there will be way more tickets or even arrest for underage drinking. As well as the companies that produce alcohol and the places where alcohol is purchase by an individual will lose a lot of business. The drinking age should just stay at 21, it has been like that for a long while now and problems having to deal with alcohol will still be around no matter what the drinking age is.
