Having been a Teacher in Los Angeles County for 24 years. I actually understand the problems faced by these Folks. (As I was told that my district had students whose primary language numbered over 50 different types.)
Especially when you come from a Homogenized society and now have to deal with a group of folks that have vastly different ideas from yours.
But their problem is vastly worse as Religion is the key factor over there. As just opposed to just language here. Although they have that problems too in spades.
All I can say is Thank God that I am Retired Now!
