The prime function of civilization is the domestication of male urges. Teaching them that if they follow the rules and control their impulses it is in their long term self interest. A society without light industrial, low skilled factory jobs cannot offer young minority males an alternative to street life, gangs, and a very violent, destructive, sexually promiscuous masculinity.
It wasn't always like this. Once Harlem was nice. Once the cities of the Northeast had stable, church-going, working class communities. Take away employment and respectable people no longer control the streets. Now idle young men do.
I remember some of that. You can't expect these guys to take faggy office jobs.
I'm not so sure about that. There hasn't been this kind of "light industry" for most of the world's history. I mean, does anyone expect us to go back to an agrarian economy where everyone had to earn a living with their hands?
