Easy for you to say, is my guess. What about the rest of us who suffer from low wages due to unfair competition? What about crime in the streets?
I posit that the ones you are calling xenophobes are not; they just want the massive illegal influx from Mexico to be curtailed.
The days of trade unions demanding exorbitant wages is over. Retrain if you can't compete with illegal immigrants, the old days will never come back.
