Edit: ^ work at a big tech company? A decent percentage of the janitors and cooks are illegal (and, for the record, are not just Hispanic)
Edit2: ^^Including themselves--because they do.
edit3: (sorry I was on my smartphone before). If the supply of jobs for illegal immigrants goes down, so does their influx. It's true in the US--and it's true in Europe and it's true in Asia: http://www.eubusiness.com/news-eu/1247156221.99/ http://www.mcclatchydc.com/2010/05/01/93137/recession-enforc...
But then, of course, in a global economy, cutting the influx of illegal immigrants (and immigration in general) would lead to more jobs shipped north/south/overseas.
So in the end, many of these legislators are really just pandering and contributing to the fear-mongering here and everywhere as people are, in many cases, naturally xenophobic.
