I am not an illegal alien nor used to 3rd world conditions, and these are not 3rd world conditions in our city. I was born in this city, AND I have travelled to Mexico. Not all of Mexico is in 3rd world condition either, although the villages and rural areas are.
What we have here is a well-functioning first rate infrastructure. As I said, if you live in slum area, then that may color your view. But L.A., for the most part, is a vital, thriving metropolis.
