First I find it funny that someone is quoting a book which was written before my time. The history books have changed alot after the secret documents of both russia and the usa were declassified. But you do bring up an interesting question. Now the world economy is more developed thus usa is only a small amount of the world, so it only produces proportionally closer to it population. Not bad for a country with only twice the number of people in Japan.
Bad money drives out good.
