[BluffTHIS!]

Every nation, ethnic group, religion and social affinity group has a culture and values. My point is that certain pop cultures and lack of appropriate values can be detrimental to any such group's economic achievement. And those things are matters of choice, not genetics or outside influences. Immature teenagers choose to listen to rap crap instead of to jazz. And if they listened to jazz or other music genres, then they wouldn't be getting a constant heavy dose of glorification of teen sex, drug use and violence.

And parents, even of low educational levels themselves, choose or not to force their kids to study and excel in academics, or to allow their kids to do whatever they want.

Any attempt to make it more complicated than that is ducking the issue and refusing to take responsibility.
