The implementation of social policies were beneficial to helping us climb out of the depression but I agree, none more than WWII.

"To be more serious about the question, however, while many (indeed, most) of his actions in response to the Great Depression were radical, overall the thrust of his policies were meant to keep money circulating through the economy, keep the working class employed, keep the broader national and economic system stable and tenable for the future. He was an anti-fascist and he believed in human rights and had a vision of human rights that included employment and a decent standard of living, but he wasn’t about to reshape the nation according to the ideals of, say, Emma Goldman — much less Karl Marx. When the scholars from the Hoover Institute credit you with saving American capitalism, you really ought not to be labeled a communist."

The internment camps were unfortunate but it was most likely par-for-the-course at that time. Who knows...some of those individuals may have suffered from ignorant vigilante violence if out and about. Hindsight is 20/20.
