Back in the day, construction jobs used to pay good money and there were plenty of Americans who wanted those jobs. I wonder what the construction job market is like now with illegals filling those jobs.
Briefly worked a job in Pittsburgh, PA about 12 yrs. ago. The company was from Texas, the super and all foremen were mexican as were 95% of the construction workers. They hired a couple of token gringos for a week and fired us because we couldn't speak spanish. Few spoke any English. From what I could gather 30-40 lived in 2 houses and were paid less than minimum wage + room and board.
Same thing happened at a local state univ. here 2 yrs. ago. Your tax dollars at work paying illegals to do a job Americans couldn't afford to do.
Victor Davis Hanson addresses this problem quite well in his book "Mexifornia".
