There’s something terribly wrong with this picture.
These schools are built and paid for by American taxpayers for American kids. They should be promulgating American culture.
Sunday to Sunday grinding school prep is not American culture.
What about soccer, marching band, scouts, and hide & seek till the streetlights come on?
It’s bad school policy and bad parenting to steal your kid’s childhood, for whatever reason.
Compared to what my grandparents endured during the depression and what others did to survive the dust bowl years in rural Kansas, those kids are on a picnic. Their parents know struggle and what it takes to survive and fortunately they're instilling in their kids the very same ethic to achieve.
But you're right, they're not succumbing to the American culture of today and that's why they're excelling in academics........
