So your argument is, hopefully I’m not strawmanning:
People who are from cultures that value education tend to be more educated.
Based on that you reject the parent’s point about education being a function of student motivation (derived via social norms acquired via their families)?
How can genetics not also play a large part in human variation?
the reality in china is that in the older generations not many people are educated because they simply didn't have the opportunity. nevertheless they still push their children to study and take advantage of opportunities given to them.
^This. Just because one doesn't have education because one couldn't afford it doesn't mean one does not value education.
I'm from Europe and my grandad, god rest his soul, a welder with his only 4 years of school which were the norm for peasant farmers that the state would provide back then, would get confused and frustrated seeing the youth of today mock and shit all over the free, state-provided education, saying he'd have given anything to be able to have the amounts of education and opportunities the youth of today have and doesn't understand how they don't value it and instead choose to disregard it and treat school with such disrespect.
Which is why he encouraged my mom and later myself to keep hitting those books so we don't "end up like him", though a skilled welder today can earn more than many professions with college degrees.
