I'd make schooling less compulsory in the sense of requiring certain subjects to be learned, and give the students control over what they learn.
It may seem like a disaster at first, but in reality, when someone wants to do something, they'll want to learn how to do it.
I feel like learning alot of useless things in high school and then getting somewhat prepared in college is really stupid when you could be learning and experiencing what you wanna do from early on if given the chance.
I remember reading about schools that ran like this in my sociology class and the kids who stuck with it were always more successful than compulsory educated children.
I think the lack of faith in a person's innate thirst for knowledge is what inhibits the education system.
