My positive message for the 4th.
A month ago, I started working a blue-collar factory job to pick up some needed extra bucks. I'm one of the few Anglos out working on the factory floor. The majority of my co-workers are Hispanic and the rest are a mixed bag of Haitians, Nigerians, Asians, and a lot I'm not sure of. The lingua franca on the shop floor is Spanish, but there are lots of other languages out there too. We deal with it.
The overwhelming impression I get of my coworkers is that they are really good people. They help me when I flounder or fall behind, correct my mistakes without getting all judgmental about it, tease me good-naturedly about being "Poppa" (because I'm not young, unlike most of them), fret about my physical well-being, and in general make the place an OK place to work despite the fact that the work is a grind and the pay is peanuts. They treat each other well too. If I were called away by my temp agency to a white-collar job somewhere, I'd miss those people. I really would. It's been an absolute pleasure to work alongside people with good attitudes.
And to those people who say they're taking jobs away from real Americans -- hey, I walked in, old white guy, nearly dead*, and got a job right way. The jobs are there. If you say you're not taking the job because the pay sucks, then say so. It's not like the people working there marched in and demanded to be paid less so they wouldn't have to work next to Anglos.
*I exaggerate, maybe.
