[Alberta's Child]

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.

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?

[Sam the Sham]

Half your labor force will be composed of people of poor backgrounds or average intelligence who require "light industry". The assumption of free trade that such displaced people would just go to community college and learn to become web programmers was ridiculously unrealistic.

Light industry has existed for most of human history. First it was called agriculture. And most factory work could be called light industry way back when. Domestic service was always primarily for women.

Half your labor force will always need to work repetitively with its hands in one form or another. A society that cannot provide stable livelihoods to people who work with their hands will be a society threatened with idle, uncivilized, young men.
