Here in West Texas, the Hispanic population, particularly those who learned English as a second language, end up in all the low-paying, bust-your-butt hard, and dangerous jobs like cowboying, oil well servicing, motel maids, nurse aides in nursing homes..... and then get victimised by loan sharks and "rent-to-own" stores and the like. A big part of the problem is education, and part of the problem with poor education is cultural, but in my looking around the real problem is good, ole-fashioned racism. "West Side Story" is about on its golden anniversary now, but Bernstein nailed it : "things can be bright in America if you are white in America!" Lots of the self-owned homes many of these folks have worked hard to get sure aren't what folks would prefer to live in.
Yes, slavery is pretty healthy. I have been a janitor, a turkey-thawer, and a giblet toter in my time, and I just can't recommend any of the three as avenues into the country club. "Giblet toter," is , however, a mighty good conversation starter on a resume.
