Every cultural/policy/etc change in society has huge delays. Especially in education - changes you implement have an impact 10+ years later. Culture, even if it's dying, dies slowly. Here in Estonia where I live at the moment educational systems is falling completely apart – overworked and bullied teachers escape from schools in unprecedented rate, there is 20% less teachers than there is a need etc. But Estonia is still in top of the PISA. Why? Because this culture of personal responsibility and valuing education is still alive in the generation of todays parents. But it's certainly dying here as well.
