i would'nt be surprised by that,
i ran a shop in cali for a long time,first as a foreman,then as a supervisor,when i first walked in the door,i ran a crew of all mexican's for about 7 years,once you gain there trust and learn some of the language,sit and drink with them after a 12 hour day,
ROOFING,you get some insight to what and how they think,and one of hier firm beliefs is that the white man or whatever is weak,we beat them a war many years ago,and they are slowly taking thier country back,meaning(CALIFORNIA,TEXAS,ARIZONA,TEXAS,)even though they will work like dogs to make consruction company owners millionairs,and execpt low wages,they are buying property and slowly gaining seats in local government's,why do you think spanish is becoming a second launguage here.
most of the guy's i worked with have strong family values and are good people. and they have an objective.
but there are the one's,just like in any race that are bad apples.
