Fortunately there is no shortage of people on the planet, and plenty of younger people who would be happy to immigrate to either of those places. "Not enough younger people in our country" is an easily solvable problem.
Assuming people are interchangeable, sure. But I would imagine Italians are biased towards fellow Italians. They don't view Italy as just a landmass, but as the people living there.
I think that's the correct term. I don't think there's such a thing as cultural homogeneity. If ethnic japanese start doing weird stuff as judged by "japanese culture", this weird stuff will immediately be considered "japanese culture", thus making "japanese culture" impossible to define precisely.
Yea...it will take quite a lot of societal change before plenty of young professionals would be happy to immigrate to Japan at least. Terrible work culture and "No Foreigners" signs chief among them.
it makes you think for a moment when a central government thinks it would be worthwhile to create a map for citizens showing where they might encounter foreigners [0]
some examples of no-foreigner signs: from 2014 [1], 2018 [2], COVID [3] [4], New Years Eve 2021 [5]
