Sowell is on to something here. The problem with Mexicans(and other Central and South American countries) is that they never really assimilate if they are constantly reinforcing their flawed culture and ideas. There are currently illegal aliens here in the U.S. that have been here over 20 years and still cannot speak or read English.
"Sowell is on to something here."
He's onto a lot of somethings. Unneeded surplus crops, free water to farmers paid for by taxpayers, and "illegal aliens" subsidized by taxpayers.
The only way around this aspect is through the amendment process...and I don't see this one changing anytime soon.
