As a slight tangent, let's remember the reason why Japanese manufacturing is so good. In the 1940s, their manufacturing was so bad that we utterly crushed them in WWII, and afterward, they said, "Damn, we need to hire the guys responsible for getting American industry to crank out tanks and planes like they were children's toys. But surely they are too busy making America great." Meanwhile, over in America, the guys who helped GM, Ford, and other companies shit tanks and planes had even more ideas to take manufacturing to the next level. The American giants told them, "Nah, but thanks for your service. We're cool with cars falling apart in 4 years." So JM Juran and W Edwards Deming fucked off to Japan and taught their manufacturing principles to Japanese industrialists. Two of the guys who took copious notes were Eiji Toyoda and Soichiro Honda. The rest is history.
