Lets see,
The illegals come from all over Mexico to the US border, by themselves.
The illegals cross the federally patrolled US border, by themselves.
The illegals disperse to every corner of the US, by themselves.
But if we remove the incentives, jobs and benefits, and perhaps even add a few disincentives, its impossible to think that they will go back home, by themselves?
How do we do the things you propose? Enforcement, ok, good, fine, but don't think for a minute many employers won't go around the system, they have been for years. We still have to deport. We have to start somewhere.
Absolutely.
