Japan’s lost generation is still jobless and living with their parents

When the discussion is about economics (the topic I have studied at uni) most comments are just plain wrong and show a complete ignorance about the topic.

If one wants a counter argument to "too many people for the economy" one can start here : https://www.jstor.org/stable/2523702?seq=1

"Using data from the Current Population Survey, this paper describes the effect of the Mariel Boatlift of 1980 on the Miami labor market. The Mariel immigrants increased the Miami labor force by 7%, and the percentage increase in labor supply to less-skilled occupations and industries was even greater because most of the immigrants were relatively unskilled. Nevertheless, the Mariel influx appears to have had virtually no effect on the wages or unemployment rates of less-skilled workers, even among Cubans who had immigrated earlier. The author suggests that the ability of Miami's labor market to rapidly absorb the Mariel immigrants was largely owing to its adjustment to other large waves of immigrants in the two decades before the Mariel Boatlift."

There are many causes explaining unemployment some due to macroeconomic factors such as the monetary policy, others due to regulations of the labor market, others due to the lack of innovation, ..... They have been studied in depth. But "too many people for the economy" is not one of them.

The malthusian argument has been used since the old ages to argue for fewer people because of resource shortages (https://en.wikipedia.org/wiki/Malthusianism#Modern_Malthusia...). It has not eventuated.

The more people there are, the more minds there are at looking for solutions to problems, the more able the human race will be. But of course, these people need investment to obtain benefit - they can't just be empty mouths to feed.

That said, many First World economies have leaded on immigration to back fill the gap of low birth-rates.

For examples:

In the USA, that's been a noticeable growth in Spanish-speaking residents.

In Germany and France, there's been growth in the Middle Eastern (mainly Muslim) residents. Needless to say, these shifts - economically necessary - have sociopolitical implications. It's possible these disconnects amplify as robotics and AI take over more and more jobs.

Japan? What would be Japan's source of new immigrants? How easily or not can they assimilate into that culture? Or is a relative lack of diversity a positive as the socio-political fabric in the West gets more and more frayed, and not just at the edges.

I mean, multigenerational households were historical norm. It is not something super special that happened just now nor catastrophy. It does have disadvantages, especially when relationships are bad. But, if you get along then it is a good thing and pretty often makes living together rational decision.

Also, every time topic of loneliness comes out, hacker news is full of lonely people talking about how it sux. One way to be less lonely is to live with other people and keep close contact with family - assuming no one is narcissist or overly controlling or something like that.
