http://www.cnn.com/2006/POLITICS/05/19/senate.english.ap/index.htmlSeems to me that the only results of making a national language is that more people know English, making it more efficient to run a government and easier for people in society to communicate and understand each other.
Both being good things.
I think we should also set metric as the national measuring system.
But for some reason I doubt the Senators supporting a national language would see the value in a "common and unifying" system.
