I dunno your country or your premise, but I can state pretty confidently that the American school system is completely and utterly failing to prepare Gen Z. Working adjacent to the schools, even amongst the best and brightest the country has to offer are thousands upon thousands of students who fundamentally do not know how to think for themselves about anything.
All this to say, depending on if you're in the U.S., things might just keep getting worse. Especially if you're living in a deeply conservative state, I would not be surprised if the number really was 90%. It's really sad, but that's what happens when you attack public schools for decades.
