Education DOES solve problems. Why do you think some of the poorest and most crime-ridden places on earth are populated with people who are illiterate or with very little education? Education does correlate with poverty levels and crime rate. It is also a responsibility that we all have as Muslims to educate ourselves both on Islamic matters and professional matters. I know that in the West, if you have any hope of having a good life and being able to provide for your family, you need to have a good education. You can't exactly support your wife and your children on minimum wage. And what if everyone did what you said? You would have no doctors, no lawyers, no scientists, no great writers, no businessmen. Education is one of the most important and one of the best things you can do for yourself.
Just because a woman is physically mature and capable of reproduction does not mean that she is mentally mature enough for marriage. Our cultures and mind sets are much different today than they were back during the Prophets time (pbuh). And that certainly doesn't mean that he is mature enough to handle marriage. If they're in high school, chances are they have next to no life experience.
The one thing that bugs me is that it seems like some (although certainly not all or even a majority) Muslim men are trying to get married just to give in and satisfy their hormones. Marriage is about things that are much, much more important than that. If you get married just to have sex, your marriage is probably doomed from the beginning. If you are in high school, I think the worst thing you could do is to get married.
