Asians are no smarter at math than white people. Asians generally just have a much better work ethic than their white counter-parts.
No one is smarter than someone else.
It is all on how you are brought up, what ethics you do for your kids, and how you apply yourself.
Whereas I spent time with my kids, trying to teach them reading, match, books, etc, and not letting them watch mindless television all the time (violent stuff, etc), others just let their kids play video games, watch crap on tv, and more.
