Stop, you are proving my points too easily.
If these folks were documented, they would not be able to walk away from their bills so easily and could get insurance from their employers without fear.
As far as living in garages go, I believe that falls upon local government to enforce, not a federal issue. Just outlaw garages.
You mean if they were legal they could then qualify for full benefits in our welfare state, and blow the California budget to the roof. You really must be blind.
