You could do your own search.
Part of that quote is here: http://www.whitehouse.gov/history/presidents/hh31.html
"After capably serving as Secretary of Commerce under Presidents Harding and Coolidge, Hoover became the Republican Presidential nominee in 1928. He said then: "We in America today are nearer to the final triumph over poverty than ever before in the history of any land." His election seemed to ensure prosperity. Yet within months the stock market crashed, and the Nation spiraled downward into depression."
You’re right, of course. I did a “google” search and Mr. Jones was the only hit.
I still think Mr. Hoover got a bad deal.
