Construct a better system, first and foremost. The fundamental problem with education in America is its purpose. We like to think it's about building a more well-rounded, intelligent individual, but that's pretty clearly a load of crap when you consider how little funding the arts get, how much of schooling comes down to rote memorization, and how little concern exists, on a systemic level, for critical thinking and analysis. It's often argued that education's purpose is to prepare children to find jobs and be competent in fundamental matters like mathematics, and while that seems more in line with how the curriculum is shaped, the fact that America lags behind the developed world in math and science would indicate that if that's the purpose, we're not meeting it satisfactorily, and there's probably an issue with the underlying structure that's to blame.
Now, what should the purpose behind education be? I have my ideas, though I'll admit they're not that well fleshed-out. Broadly speaking, the purpose we like to say education serves - building a well-rounded, intelligent individual capable of critical thinking - seems like a good one, it's something on which I can definitely sign off. I think that "creating workers for the industrial machine" most definitely should *not* be the purpose of education, though, and the fact that it is - and that the only people in the country with the power to change that purpose don't want to change that purpose - is enough to say scrap the system and start over.
I halfway expect Putin to come in here with his "If you don't put forth an alternative your position is useless" line, so I'll go ahead and pre-emptively say that if status quo is making things worse than they would be if we did nothing, then "doing nothing" is a valid alternative which must be adopted. Here, at least, I think that holds.
