My conclusion is that AZ, NM, Texas and probably California would
grind
to a halt without the illegals doing all the 'scut work' jobs.

No, the greedy business owners would just have to start paying a wage
that Anglos would work for. It's just like the landscapers where I
live. Landscapers are charging a fortune but are hiring illegals to do
the bull work. Then the "landscaper" is pocketing the majority of the
outragous money he gets from the stupid homeowner. They charge a
$1,000 to dig up a few old plants and replace them. The illegals go
home with fifty bucks.
