I think it was designed to be this way.
This supply of cheap laborers helps to keep the inflation down which we need desperately, because heavy gov spending encourages inflation. If these illegals were all professionals and trained people pouring into the US, then they would encourage inflation, but the fact that they are not makes the whole situation different. They actually help our economy (as long as they DO NOT CAUSE more gov spending).
Approximately 28% of all all prisoners in our prison systems are illegals.
To state that having illegals here actually helps our economy is concret evidence that you have what is commonly called "Head up Arse" syndrome.
