Interesting take. Certainly there's those who could work and instead reside on the government dole. Are there as many in the fit to work but choose welfare camp as there are immigrants toiling at low-wage jobs? I doubt it. A few things, AAA. Firstly, the thirty years since Roe v. Wade has really caused a reduction in American population growth. In the great Northeastern metropolitan areas there's very little in the way of poverty level whites. That leaves blacks as the prime candidates for the lowest of low wage: housekeeping, kitchen/janitorial help, ect. It's just not realistic to think Americans, no matter what socioeconomic class, are going to work those type jobs. Hence the Mexicans, Poles, Haitians and Bosnians. It takes a labor Army to satisfy the needs of todays yuppie bourgeois. Maids, au-pairs, gardeners, parking garage attendants, towelboys at the club(s), busboys, chicks working the counter at Starbux. My IT guy is the only one making nice $ and he's often the only one who's white-Anglo. When economists talk about "consumer driven" they're not just referring to the sale of goods, we're also talking JOBS. One may ignorantly lambaste "tax cuts for the rich" but those upwardly mobile are employing zillions of lesser folk.
