You mean the one 'muricans can't speak due to an abysmal education system. There's the unchecked immigration to consider as well.
English as a second language by 2020, calling it
Hmm?
Most Americans can speak fairly good English. With 300 Million people, if but 4% are incapable, that's more than most countries in Europe total population.
Also, I'm not sure, but I believe these tests do not measure actual RL capability of communication. Written communication, even in English, is easier than having to talk in English to others(if as a second language). Many of us on this board, due to Vidya Game culture, have to learn and understand English. This does not translate into speaking it effectively, though.
Why am I responding to the USA Trollbait...sigh.
