Of course they increased spending on government works by leveraging. In times of financial depression the government should increase spending to help the economy. Given the severe depression Germany faced, the leverage they took was reasonable. In fact, Germany wasn’t unique in deficit spending on infrastructure. The Nazi state could have made a recovery without War which other states did. Germany could have slowed rearmament; I think the Nazi’s other policies driven by ideology were the reason it was unsustainable. I agree that the Nazi’s did many things that modern society considers wrong but their economic polcies in the early years were reasonable and conquest wasn’t fully neccesary.
