Central planning only worked because it was war time and everyone was willing to put aside their life and deal with a lower standard of living for a short time to help Japan and Germany find out after fucking around. If you only focus on the positives of how ridiculous American war production became it seems great, but return to reality and it becomes clear that it wouldn't have been sustainable in the long term considering how people were having to compromise with rationing of basic goods like fuel, sugar, meat, metal, paper etc.
