Then I am sure you enjoy the endless wars and reagans military build up right? Didnt think so. A common theory on why we finally recovered after a world war instead of the decade of keynesian economic theory. War rationing forced saving that built up over 4 years of war. And it was unleashed on the economy after the rationing was lifted and industry went back to building consumer instead of war related goods. It also helped we were the worlds factory.
Instead of being the consumers, we were the makers. Instead of buying on credit, everyone else was buying from us. Makes a huge difference indeed.
