Very true, it's how we crushed the Japanese, too. They were almost literally clearing neighborhoods for reclaimed metal and wood, converting entire towns into production facilities and even with that, they paled in comparison to the productive giant of the Goblino. Their zeroes might take 3 planes out of ours, and we would replace them three-fold and with more experienced pilots. They were forcing young pups into dilapidated old craft at the risk of great military disgrace to Kamikaze us because they knew they had no better options. The horrors we faced in the Pacific were truly abject, but it still would have been remarkable to be a wallflower back then and see the collective gusto that we managed to pull together, and all while still maintaining a perfectly functional economy with a massive swathe of our workforce overseas. I read somewhere that the US was using not more than 20% of our manufacturing capacity towards munitions and craft, and even then we were absolutely devastating the Axis.
