That is the biggest part of it, the family influence. I did a study once on Korean children, why they do so well academically in the U.S. It's the family. Education is highly valued in Korean tradition, it was the way to get ahead for the entire family. The children are expected to do well in school, no excuses. And they out-perform whites and blacks in this country because of their traditional family values.
They then turn around, and perpetuate the rot in the education system by voting for democrats.
