Two big problems, money and personnel. The education system right now is losing funding from both federal and state so that leaves private, that's why homeschooling kids and private schools usually pumps out better students overall. Personnel is the other biggest issue, to have people who knows what kids do in administration is extremely hard and not to mention even we even need those types of teachers. To properly provide an environment to nurture students, a teacher needs more than just an license to teach and be able to provide more than education but social interaction as well. Most people know it's a problem, the problem is this thing will take much longer to change than phones and cars.
