My bad, it was meant to be 2080 but I can't edit the post anymore.
Either way, japan's population is not only ageing but declining at an exponential rate due to low childbirth - which has been directly attributed to the piss poor work life balance. The Japan as we know it today will not exist in a few decades. It will either be a far less populous country, or full of immigrants.
So I don't think we can take their 'not us vs them' attitude in the workplace as any kind of precursor for a successful or happy society.
