"Where are you going to imprision them? We dont have enough prison space to house all the criminals we convict. Where are you going to house all of them as they await trial? You do realize you cant just scoop up people who dont have papers on them and ship them to a foreign country. Face it people, if this was as cheap and easy as you think, someone would have done it already."
There is a cheap easy way.
Enforce existing laws for employers. I own a small business, it's not that hard to find out if someone is here legally. (Nexus) The illegals will self deport if there is no work...and no goobermint handouts.
If the job market dries up for illegals and we find that we DO need 20+ million dish washers and lawn cutters, then by all means start a guest worker program.
And what percent are working for individuals directly and being paid in cash?
What are you going to do about laws that prevent discrimination on goobermint handouts on basis of being illegal or not?
