The ironic thing is the liberals who support illegal immigration for their own selfish needs are treating Mexico's welfare class like indentured servants. They are the real racists.
One thing I've noticed about the average liberal: they're narcissists. And narcissists are unable to empathize on any real level; for them, any "empathy" that they display for the downtrodden is largely a matter of political posturing - a way to go with the herd, to "be cool". They have no problem paying illegals substandard wages and working them to their advantage - I could give you three ugly examples just from my neighbors and ex-friends (like the hyper-liberal wife of a good friend who crowed over the fact that she only pays "Juan Renteria and his crew" $20/Mo for yard maintenance. When I said, uh, those are illegals he's using, she got defensive and used the usual dodge:"well, I can't tell him how to run his business").
Are they racist? I don't know...I doubt if they invite Los Inmigrantes over for dinner. But they clearly have no interest in their well being, and seem to exploit people just as avidly as the mean old Right Wingers supposedly do.
For the record, we pay rather higher rates, and I demand no illegals from contractors. Interestingly, I get a much better group of people doing the work, who can ad lib and have real skills doing what they do.
Ya gits whats ya pay fer.
