It may be practical but a lot of people bristle at the 3rd world invasion. Every other culture comes here and is expected to learn the language except for one and we continue to accomodate and relinquish some of our identity.
Really? Have you read the plaque on the Statue of Liberty?
Do you realize that most of the Southwest was stolen from Mexico?
Consider this in the State of California where we embrace other cultures and languages Spanish, Chinese, Korean, Tagalog, Persian, Russian, Vietnamese, and Thai appear in official state documents, and the Department of Motor Vehicles publishes in 9 languages.
Just saying it\'s not just Spanish though over 12 % of the United States speaks it as the second most common language which to me makes it a pretty good idea to be somewhat fluent in it.
