I was wondering if the effect of valuing education is subject to survivorship bias. Take China for example, on average 50% of the grade-9 students have to enter vocational training schools instead of high schools (grade-10 to grade 12). The odds of getting into the top 33 universities in China is less than 2%, and the odds of getting into the next best 100 universities is less than 4%. I'm sure more than 6% of parents value education to the extreme, yet large number of students may not get what they desire no matter how hard they try.
