Franklin Delano Roosevelt was President of the United States during the Great Depression. In response to the worst economic crisis in the history of the United States, he implemented his New Deal domestic agenda.
A fundamental part of this deal involved putting money in the pockets of impoverished Americans in a manner that did not impugn their dignity. To that end, he sanctioned State programmes that paid one group of men to dig up holes in the morning and another group to fill them up in the afternoon. Neither group was aware of what the other did, but they all derived immense satisfaction from earning what they believed to be just pay for an important national exercise.
