Come out to CA or AZ and see for yourself how bad it is. We had a public hospital close because of the cost of treating illegals. To be a manager at McD's or any other fast food place, you must know Spanish.
I live in the suburbs. A local chain of 10 Mexican Restaurants (all in the suburbs) closed up because about 80% of the staff in the whole chain were illegal.The Mexican gangs are worse than the Crips or Bloods because they don't care who they kill.
