I agree to you to a point, but will never sacrifice the status of America as a culturally western country to $$$$$ or meritocracy. We used to ban Asian immigration to the country for a few reasons.
Watch Asian dramas. You’ll see that tiger moms are not the exception but the rule. Children are trained from babyhood to do nothing but study until they finish high school, if not going further, or college. Minimum social activities. No dating. Almost no life except passing exams. A child that can support itself well, can also support its parents’ old age.
It’s not that the culture is genetically smarter, it’s just that the lack of social security has created social requirements to push each individual toward as much success as possible.
America is a melting pot and it includes Europeans, Asian and African individuals, etc. And it maintains each culture until the next generation is assimilated. A few generations here and the tiger moms will likely gradually assimilate, too.
The problem is that the 1960’s radically changed our culture and we still haven’t solved the problem my generation caused. If you’re nostalgic for the old morals and societal standards then, again, watch Asian dramas. They espouse the moral standards that we’ve left behind. Unfortunately, you can see Hollywood nibbling at the edges but the old men that run China are still using authoritarian rules to try to hold onto the old moral standards for a while longer.
We don’t need to worry about cultures overwhelming American culture. We just need to worry about the current educational system teaching defeat to our next generation. Trump wants to eliminate the Education Dept. More power to him! He has his finger EXACTLY on the problem and needs our support to eliminate the radicals of my generation.
