> isn’t America’s acceptance of failure often cited as an element in the success of its entrepreneurial spirit
Yes, the parent comment is entirely wrong. The US culture is hyper accepting of failure compared to most other prominent cultures, including Japanese culture (which in fact does not tolerate failure very well at all).
America accepts failed ventures, not individual mistakes. A business that collapses is a learning experience. But, while they are operating, a business must never admit to wrongdoing impacting customers or the public. There is great respect for failed business judgment, but very little for weakness.
And, wrt to samurais and failure, seppuku?
