I agree that cheap labor is part of the problem. The person who suggested huge fines for those who hire illegals is right. That would solve part of the problem.
The migrants who came to pick tomatoes are a different story. These people traveled with the crops to eek out a living doing back-breaking labor that no one else would do. They are hard working people who didn't/don't abuse our welfare system or take advantage of our free health care paid for by the taxpayer.
The problem today are the illegals who bring huge families, have baby after baby and you and I pay for it. Make no mistake. Some come to work but with a large family and only one or two working, they need assistance. How many times have you seen a young Spanish girl with several small children? I may sound harsh, but it is time to put an end to catering to the people who choose to break our laws.
Now I step down from my soapbox.
