The problem at the core is that education has ossified. A toxic combination of parents unable to accept that their children can have a better school experience than they had ("we had to hike two hours even during storms to go to school, stop complaining!!!"), privileged parents wanting to keep classist privileges for their children (this is a huge problem here in Germany where we separate between useless Hauptschule, just as useless Realschule and Gymnasium after 4th/6th year), politicians intimidated by the huge influence the well-networked classist parents have, underpaid staff and underfunded schools, burnt-out teachers who long since have given up on changing anything because of the lack of time, funds, respect for their work and backing by superiors...
