I believe this is a bit of a moot point until teachers start getting paid what they deserve. Yes, the ideal would be to better prepare our young adults for the outside world but there is always going to be someone demanding where the money is going to come from. All the while, teachers may get some recognition and accolades but it's mostly just for show. Cut useless military spending and stop allowing our elected officials to give themselves raises on a whim and truly start investing in our youth.
Personally, I think more trade skill classes and introductory courses to business, science, and arts of all kinds should be offered. Let the young adults see what they may show an aptitude for and might be willing to work harder to achieve.
In the end though, unless we are willing to follow through with the funds and work towards making sure all students are afforded the same opportunities regardless of income, race, sex, and cultural background, I believe nothing of substance will get done.
