The works progress administration, the civilian conservations corps, and aid to dependent children were established during the administration of:

The Civilian Conservation Corps (CCC), Works Progress Administration (WPA), and Aid to Families with Dependent Children (AFDC) were programs created during the New Deal during the administration of Franklin Roosevelt. The CCC was created in 1933, the AFDC in 1935, and WPA in 1935. The CCC and WPA were established via Executive Orders, while AFDC was part of the Social Security Act of 1935 which is signed into law by FDR.

I believe the answer is Democracy.
Before the creation of democracy, all of the regulations that created within the nations is made solely by the king/emperror with the help of his Advisors.
After Democracy, each citizens in the naton now has the right to be involved in the governmental process through their representation.
