All I can say is no one told Toyota.
They have moved a lot of manufacturing to this country. I just read a story about a GM factory manager who was improperly fired from her job at the GM plant. She found a job at Bodine Aluminum(a Toyota company) and raved about how happy and inthusiastic people were at the Toyota plant as compared to the GM plant. I have taken the tour of the Toyota fork lift plant in Columbus Indiana. Everything is as the book Gung Ho would have it. And they arguably turn out the best forklift in the world. It is clean and happy and motivated.
