The ones that come here legally do. The illegals are in it for the free stuff.
Most of the illegals that I've met come here out of desperation.
The liberal government agencies (in California) are quick to sign them up for benefits and advise them of their "rights" and to make sure that the evil employers do not take advantage of them.
Meanwhile the conservatives (rightfully) complain about them being here illegally and shun them.
It is like watching a slow motion train wreck.
