If the United States haven't grown poets, on any scale of grandeur, it is certain that they import, print, and read more poetry than any equal number of people elsewhere -- probably more than the rest of the world combined. Poetry (like a grand personality) is a growth of many generations -- many rare combinations. To have great poets, there must be great audiences too.
