Ya, how would the generation that had just fought WWI have any clue about rhe cost of war?I disagree. It was done for political reasons, because the public wouldn't stand for the tax increases required if they knew the true cost of the war. War socialism allowed the politicians to hide the true cost from the taxpayers.The US had to implement a lot of socialist policies during WWII, like a planned economy and making factories only produce certain things and so on.
I'm not criticizing though, that was the only way to win the war.
