Collinsworth says, entirely rationally from his perspective:
Progressives need to start talking about illegal immigration. My dad says we should do this because it’s the perfect wedge issue with which to divide the right’s unholy union of corrupt corporate superpowers (pro-immigration—cheap labor) and white working-class middle Americans (anti-immigration—not so hot on new competition or new cultures). I say we should do it because our own values demand a better way
But I don't really have any hope. Of course, progressives should be interested in immigration reform - and were, during the 1880-1920 Great Wave. You meet individual progressive immigration reformers, like the Collinsworths, all the time. But the modern leadership of their movement seems impervious, perhaps because their motives are different. In the end, immigration reform will probably have to come from the Right.
