Answer 2

Keep in mind that in 1914, 30% of the world's manufacturing capacity was in the US. As soon as the war broke out, the US economy was involved at least in selling arms to the Allies, as well as lending money to the Allies. Britain, especially cashed in its investments in America and borrowed heavily from the US government and Wall Street.

In essence, the US economy was mobilized for WWI well before the rest of the country.
