Because libs have told them that they don't have to speak the language and our government will take care of them since they will be unable to function, let alone succeed, here because of it. As Chi Girl explains, those who speak English and something else don't have to abandon their first language. They can speak it at home and at functions like church or meetings, etc. My husband, who is from Puerto Rico, speaks nothing but Spanish with his family when they are together. Yet, his parents knew that if they were going to function here, all of them had to be able to speak English--and they do. Those who refuse to adapt cannot function yet we have decided to pay from them to exist rather than insist that they learn to function for themselves. Foolish.
