Whites respect them for it. I meet a fair number of people who hire unskilled or semiskilled labor. Without exception they report that Hispanics show up, work hard, and don't have attitudes. Blacks, say employers, don't show up, don't work hard, quit unexpectedly, and tend to be surly. The result is that, hereabouts anyway, Hispanics have taken over the low-end job market.
Blacks resent it.
If Hispanics succeed in moving up, which they seem to have in mind, blacks will simply be bypassed. No alliance there. Last week, Radio Novecientos asked callers, many of them on cell phones on the way to work, to recount their successes in this country. I didn't transcribe calls. Now I am assistant maintenance manager, and if I can get a little better in English, I think I will be the manager soon.
