based on your description, one reasonable way to 'revolutionize' school might simply allow people (who don't want to be there) to leave.
They were already at a University. None of the students were required to be there. They all had the ability to just leave.
There has been a shift towards too many jobs requiring a tertiary education.
But good luck reversing that trend.
That might be fine for someone in the wrong college degree, but I - as a tax payer - need every sixth grader to learn essential the same things. I need kids to grow up able to provide life support for themselves so I can retire as by body fails from old age. I'm investing in the future of many kids I otherwise don't know or care about because making their life better makes mine better.
Even in the case of a college degree some are better than others
