Many of the original New Deal programs required heavy manual labor. WPA workers built hundreds of schools, health clinics, roads, park facilities, and community centers. Much of what we now call our 'infrastructure' - highways, buildings, power plants, etc. - is here thanks to thousands of WPA workers.
When I was very young, most of my childhood heroes wore capes, flew through the air, or picked up buildings with one arm. They were spectacular and got a lot of attention. But as I grew, my heroes changed, so that now I can honestly say that anyone who does anything to help a child is a hero to me.
