What does "qualification" mean? Are employers not allowed to hire individuals who have not earned a government-funded secondary education qualification? No? (Because that seems rather authoritarian.) Then what's to prevent privately-funded secondary schools from issuing their own graduation certificates that employers take seriously or not depending upon whether the privately-funded secondary schools are perceived as producing quality graduates? Finland still permits private universities that charge fees - Are you going to outlaw those, unlike Finland? No? Then what prevents a private university from accepting students without public school "qualification"? I think that Finland seems rather homogenous about public secondary schooling because it's a rather homogenous society, not because it's actually forbidden anything. It's just social pressure and norms, not "law". Which means in less homogenous places like most of the rest of the world, you need either to outlaw private universities or employers hiring people without a public secondary school qualification, or permit private schooling. I have my own proposals for a more decent schooling system here: https://medium.com/non-violence/stakeholder-control-democratically-funding-primary-secondary-education-without-coercion-ee4c377eedf7
