I'll say it, even recognizing the peril of being banned forever- it's the children.
Given that K-12 education is largely sub-par, that the popular culture celebrates ignorance, selfishness, and gratuitous stupidity, that our political establishment promotes the racial, social, and economic balkanization of the society, with all of the concommitant issues; given all of that, the result is children, especially male children who never grow up, never care to grow up, who are less and less able to see the world beyond their own immediate desires. Sort of like babies. Or dogs. Not prepared for the ASVAB/AFQT, or even prepared to understand the necessity of such a thing. And it seems that there are plenty of people in positions to do something about that who are completely cool with it, for reasons that escape me entirely.
