Was wpa successful? why or why not?

Headed by Harry Hopkins, the WPA provided paid jobs to the unemployed during the Great Depression in the United States, while building up the public infrastructure of the US, such as parks, schools and roads. Created by President Franklin Roosevelt to relieve the economic hardship of the Great Depression, this national works program (renamed the Work Projects Administration beginning in 1939) employed more than 8.5 million people on 1.4 million public projects before it was disbanded in 1943. The PWA spent over $6 billion but did not succeed in returning the level of industrial activity to pre-depression levels. Though successful in many aspects, it has been acknowledged that the PWA's objective of constructing a substantial number of quality, affordable housing units was a major failure.
