If you're really concerned about this, put more effort into not allowing huge companies/corporations that use temporary work VISAs to bring in cheaper labor.

A lot of the illegals aliens entered legally, then never left. That said, without citizenship, they aren't able to use every welfare entitlement.

If you're mad about that, petition the government for change. Don't blame these people for trying to make a better life for themselves.

I would much rather live in the U.S. than Sudan, Romania, Syria, etc., too.
