In general you're correct though the US was probably a special case during WW2. The US benefited enormously from being the only industrial power to end the war with no significant loss of territory or industrial capacity. Casualties were also relatively light with only 0.32% of the population dying due to the war. During the war making use of women and other groups that normally wouldn't have been working would have also offset some of the production losses incurred by sending young men off to fight.
