My opinion is based on several years living in Korea and about 6 months in Japan, plus a few more years working with Japanese and Koreans. I think it accords with the view most people with direct experience of these cultures have, including many natives. A lot of people are in awe of Japanese and Korean culture when they first encounter it, but most people acquire a more balanced view after they dig a little deeper. Lots of good things in both cultures, but also lots of quite negative stuff.
If they don't see a different manner of thinking and doing things, they continue in the old patterns. If they see another way, they can make an informed choice. A high proportion of younger Japanese and Koreans who spend time abroad do not want to return home to live. This is especially true of young women.
I agree there is a very disturbing trend to censor academics and free speech on campuses across Europe, North America and Australia [including NZ?]. It must be resisted. But the right wing censorship and political correctness from the right/establishment should not be ignored. It's just that the former is new and stands out. Plus, media outlets get hysterical about it. It is a thing, it's a big deal and it needs to be countered, but it's part of a wider problem.
Not all the counter culture activists of the 1960s sold out. There were a lot who were just following the trend and joined the mainstream as they grew older – but plenty held true to their principles even if they had successful careers.
I'm no fan of globalisation. It's just a way for big companies to get round environmental regulations and labour laws.
I think we are arguing at cross purposes to a very great extent. My main issue is that ethnically homogeneous populations are not the ideal model and more diversity [properly managed] would be good for them.
In the case of Japan, for example, it would be better if Japanese women were allowed to wear comfortable shoes and clothing to work, and not wear make up if they prefer not to, especially if they don't have face-to-face contact with customers. It would also be better if sexual assaults were treated more seriously than minor drug offences.
If Japan saw how much more productive workers could be if they worked standard hours and could leave work on time, rather than stay until their boss leaves even if they have nothing to do, that would be a HUGE step forward.
If Japanese and Korean education could learn from more learner centred approaches and focus less on memorisation and standard tests it would go a long way to creating the work forces they need for the future.
I could go on and on, but you get the drift.
In the meantime, they can retain their art, music, food, etc. Those are positive aspects of culture which should be preserved.
