And by the way their wealthy counterparts in Latin America send their kids to private English schools!
A little aside...
My wife is a school teacher in a fairly heavily Hispanic district. She took an ESL (English as a Second Language) certification course in order to get a bonus at work and presumably communicate with her kids in Spanish. On the first day of class, and without any hint of irony, the teacher said “Today is the last day that we will speak to each other in English - from now on Spanish only. The best way to learn a language is to immerse yourself in it.”
Public education at its finest.
