Oh, come on. Very few Americans have the property or skill to grow their own produce. How do you expect city dwellers to grow produce? Esp. those in Northern climates?
But, for sure, states who grant benefits to illegal immigrants are causing a problem. Why not have a legal guest worker program where they don't get benefits?
The biggest problems are in Liberal states.
Do you really think that people are so inept as to not be able to grow tomatoes, beans, or lettuce in their own yard? We certainly grew our own where I was raised. It's a bit of work here and there, but it certainly isn't rocket science.
What skill? You plant seeds, you weed, you water--and you're rewarded with good eats--and flowers, too, if desired. I have lived in northern climates, and gardened, as did my neighbors, I might add. The thing is, you do have to pull yourself away from the teevee and/or the video games, and you do have to invest a little elbow grease--the lazy wouldn't fare well in this endeavor.
