I can remember working construction in Houston when the border patrol raided jobs, and actually hauled the illegals back to Mexico. I also remember that on average those that wasn't ready for a vacation would be back in three days. I can also remember when school teachers south of I 10 did not have to be bilingual to be considered for a job.
Anybody that thinks Texas hasn't changed (not as fast as Cali) is not living in the real world.
I was born and raised in Texas, as my faminy was for several generations, but I watched it change enough, that I hope never to have to live there again, I do not think illegals had that much to do with it near as much as folks moving in by the hundreds of thousands from other states, bringing their thinking of how it was done back where they came from, including on how to deal with the illegals crossing the border, which Texas had dealt with fine since it before it was ever a state.
I also remember how HOT it is in Texas, also how cold the West Texas wind can be. lol
