English is useful because the 26 speakers tend to give benefits to only 26. They thinks "a/an" is the best words of all languages.
"Back and deep down on the tie-ribs of consciousness, in the mind, say, of the English-speaking race, was a capacity to thrill to short, Saxon words; back and deep down on the tie-ribs of consciousness of the Chinese mind was a capacity to thrill to its own hieroglyphics; but the Chinese mind could not thrill to short, Saxon words;"
————Jack London
it's obviously FALSE! but it's just the racism of 26 letters make them stronger.
But for other languages, even you learned them, you can not get a better treatment.
So it's because the racism of English let me speak more English.
