One of my favorite memorials is to FDR. This is tucked away on the side of the Tidal Basin. Now it's a few short steps from the King Memorial. I think it really shows how great a man FDR really was.
I found the quote bellow to be particularly appropriate for the times.
No country, however rich, can afford the waste of its human resources. Demoralization caused by vast unemployment is our greatest extravagance. Morally, it is the greatest menace to our social order.
