@teenyboone,
teenyboone, There are jobs even legal citizens of this country will not apply for, and that includes the food industry. Speaking from personal experience, my siblings and I worked with Hispanics and blacks harvesting fruits during the summer months when we were children. Its hard work that required long hours from sun-up to sun-down. We were never aware whether those working with us were legal or illegal immigrants.
It's no different today; many of our fields and farms will be empty of workers without those willing to work hard and long hours to feed all of us. People who purchase fruits and vegetables can't seem to realize the obvious when they go to the supermarket to buy produce.
Nobody asks if they were harvested by legal or illegal workers, but complain about illegal workers.
As georgeob succinctly put it, it's a political issue that our government has failed to enforce for good or bad. Those looking at the new immigrants as creating most of the crimes are dead wrong.
It's a simple matter of looking at the large cities of our country where most of the crimes are committed; they are not the new generation of "Americans" who commit the majority of them. If one looks at California as an example, most coming from the Far East usually end up going to the best colleges and universities of this country. I'm also sure there are incidences where they also commit crimes.
Welcome to America.
