> And in which countries?
Well I'm not sure there are many countries that can compare to Japan's homogeneous cultural ethic, it really is unique in many ways.
I put integrity in quotes because the very concept is pretty nebulous, especially when crossing country boundaries. But, I can concede there's at least a general understanding of the word, and I can't say that's what motivates people to do good work/be productive.
At the very least, it's not the only carrot, and you're completely forgetting the stick (which of course, is discouraged these days, but it definitely has it's uses).
I often see a similar argument from gun nuts. You show them that Japan has a ban on guns and that they have zero hand-gun related deaths annually, show them that they have among the lowest crime rate in the world, and they use the excuse of "Oh, it's a different culture. It's not comparable". That's nonsense logic to me. All it means is we also need to change our culture too, then. Sure, it's another factor to consider, but that's all. It's not a roadblock.
Here's a nice quote from Akio Morita (Sony co-founder):
"In my view, profit doesn’t have to be so high, because in Japanese companies our shareholders do not clamor for immediate returns; rather they prefer long-term growth and appreciation. Of course we have to make a profit, but we have to make a profit over the long haul, not just the short term, and that means we must keep investing in research and development."
Can't say the same thing for USA.
