This is a quote from a speech he gave in 1948. Too bad we can't hear him today:
“We have forgotten that we are our brother's keeper, we have forgotten about each other. We are the victims of neglect, we've neglected cities and farms and people, the children and the elderly, and we have had as a measure of our success that those who already have too much will get some more, that's right, rather than those that have too little shall get enough. And the real test of a progressive, a liberal, and the real test, if you please, of a man of spirit, of faith is that he sees to it that those who have little get enough.”
Hubert H. Humphrey May 27, 1911 - Jan 13, 1978
Rick Perlstein in the New York Times says it better than I ever could.
