I have read about Korean immigrants in Los Angeles learning Spanish as a second language in addition to their Korean language. They find that Spanish is easier to learn than English, and in Los Angeles there is no need to speak English.
Quite true. Just today I was having a conversation with two coworkers. One is an immigrant from the Philippines. Her English is already very good, but she wishes it was better and is trying to improve. The other coworker was born here and said she feels ashamed to be living in Los Angeles and not knowing how to speak Spanish. I kept my mouth shut, but I live in LA and I refuse to learn Spanish! Why should I have to learn a foreign language in order to get along in my own country?
