in california i go to a grocery store, auto service, hospital or public agency and well over half of the people there speak a foreign language or speak english with a foreign accent. some are impolite / uncouth in behavior to the point of being pathological.
Ditto Northern Virginia suburbs of Washington, DC. We spent 7 months there in 2015 and I was surprised and appalled at the absolute foreign and unpatriotic nature of that area.
