Quick Wikipedia Summary:

The Civilian Conservation Corps (CCC) was a voluntary government work relief program that ran from 1933 to 1942 in the United States for unemployed, unmarried men ages 18–25 and eventually expanded to ages 17–28.[1] The CCC was a major part of President Franklin D. Roosevelt's New Deal that supplied manual labor jobs related to the conservation and development of natural resources in rural lands owned by federal, state, and local governments. The CCC was designed to supply jobs for young men and to relieve families who had difficulty finding jobs during the Great Depression in the United States.

In the US, we have many infrastructure programs falling to the wayside such as old and failing city water systems, electrical service, and outdated public transit.

I understand the maasive ammounts of money and coordination has to go into a project like this. But to me, introducing a program like the defunct CCC would allow struggling Americans to have a steady path of employment throughout the nation. More money in the workers pockets, less unemployment, and an improved society afterwards. This to me seems like a win win win, what am I missimg here?
