This is some asinine cultural analysis, as if entire cultures can be reduced to the embrace of moral philosophies. You could just have easily described China as harboring a deontological commitment to social harmony and deference to authority, or America as being consequentialist in its embrace of freedom as the approach most conducive to happiness and opposed to tyranny. Both are caricatures, of course.
A problem I’ve noticed with philosophy nerds is that they have a tendency to overemphasize the importance of their niche interest by hallucinating the influence of philosophical reasoning in human affairs and historical events. Most people in most times don’t think about this stuff at all. It’s completely irrelevant.
