I don't know if you're being sarcastic, but it's an EXCELLENT IDEA, If they saw what life was like in the African country founded by former slaves they might be a bit more respectful of what it takes to maintain a civilization. They'd be trained and come back with a job skill, and some knowledge about how to keep their communities clean and safe. For those who aren't working, the feds are supporting them anyway, so they might as well be training them to do something and let their salaries pay for their freebies.
My cousin’s daughter went to Kenya (I think, somewhere in Africa) to teach the natives how to raise chickens. This is a girl who grew up in the suburbs. Now she has a job in Washinton DC probably as some sort of community organizer.
