How many people illegally moving in from Mexico have IT degrees and/or experience?
There are plenty of illegal immigrants (especially in IT) from places other than Mexico. Why no obsession with the illegal IT workers I've worked beside from Canada, Ireland, Australia, and especially India?
Although IT has higher pay rates than middle income construction or low income cleaning office buildings, I've seen exactly the same employment dynamic in those and other sectors outside IT.
One of my underemployed school-dropout semi-literate American tenants was unable to pay his rent. (I rented to him precisely because his underemployment was the National Guard. I had been discriminated against as an Army guy in the '60s.)
I suggested he take a well paying unskilled construction position for a 2 year project that was unable/desperate to find workers. His response was that he didn't do "spic" work. Sure enough, after many ads in the paper and pleas to the local unemployment compensaton office, the only people the project could find to work were (illegal) immigrants... but not Mexicans.
The same is true of the illegals who clean office buildings. When I worked in Chicago's loop, it was mostly illegal Poles cleaning offices. But you would never know they were illegal because the local Democrat political machine sold them Social Security cards, Drivers licenses and voter registration cards for cash ... and the obligation that they vote for the Democrat machine candidate in every election.
