Burning a system to the ground is almost always the best way to turn a bad system into a worse one. Just like the junior devs impulse to tear out the bad code some other guy wrote and replace it with the differently bad code that they wrote.
Refactor. Don't rebuild. The bigger the system, the more true that is.
Code is logical, people are not. Cultures can only be removed, you will never convince a 40 year old woman working in education their whole life that their entire philosophy is wrong. They will continue to push their beliefs under the table. That's the poison that is naturally bred in public institutions. It's all politically motivated.
Not that I vote for them but you can see how little of a dent Trump made because the institutions around them were actively undoing their work. Perhaps for good reason, however they were voted in by half the population. What we see for support in education is largely confirmation bias. If you put it to a public vote higher education would be defunded.
Refactor. Don't rebuild. The bigger the system, the more true that is.
