They have a different culture and values, the US’s strengths lie in individualism and the character of the individuals that live here, and that’s both good and bad. But it’s entirely unsurprising that when responsibility and ownership is sharded up into trillions of tiny pieces and diffused that the outcome is awful.
I'm certainly a fan of Japanese products. They are high-quality, etc. And everything was clean and orderly and amazing as a short-term visitor over 20 years ago. I would not be quick to say it is a better culture though, I suspect some negative are quite hidden, and lurking underneath the cultural norms. Again, as an outsider, I have lots of positive thoughts about Japanese culture.
