That all sounds like you're saying: if people are ideally educated/informed/fit, then good government will follow. But that's what communism has been saying for decades, in a way. In fact, any system will work if people are educated/fit.

That's why a system whose success depends on ideal citizens is probably a bad system. And it's also why a good system will always prioritize education, by any means necessary: because that's the thing that will most likely guarantee its continued existence - because even if there are better systems out there, change requires effort, so citizens, like Nature, will prefer to tinker rather than redesign from scratch. So a less-than-perfect system that prioritizes education will tend to remain in force. Radical change happens usually when things get really shitty. (Hence the anarchists who wanted Trump because they think doomsday will ensue while he's in office.)
