Some areas are much worse than others...we don't have the transient field workers here that are the prime examples of what you're talking about. While I'll not claim our local packer is lily-white and fully enlightened, they also aren't nearly as manipulative as many I've heard of. While they're demanding in terms of promptness, etc., the wages and benefits are far from poverty level even for those on the kill floor and opportunities to move up within are available...a little more foresight in some areas could probably reduce their turnover significantly, though, so I'm certainly not saying they're anyways close to perfect...
In general, I agree although there are significant numbers here that going to community college and the bulk of the kids are doing pretty well in school...of course, intermediate sized communities can assimilate easier than either very small ones overwhelmed or huge ones who already have similar problems. In this area, they do have a decent wage and the opportunity if they take it to make something better for themselves and their kids. The only thing that really bothers me off is that there are a significant number of illegals who don't go through the system...that is a constant source of conflict within their community, as well...

If one were serious about that, there is education that can help with a lot of the experience/knowledge thing. There are opportunities in areas such as here to work for/with existing farmers who have no identified family members to take over. It would be a sacrifice for a while, but I'm aware of a number of these. Of course, there would be a shock in coming to the high plains from back there... :)
