Tokyo, Japan: metropolis of 40 million people

Their minimal and wooden architecture surrounded by nature back then looks so much better and beautiful than those ugly glass buildings before they got westernized.
 
Tokyo’s gdp is half of Japan’s total GDP :ooh:
Greater Tokyo has forty million inhabitants, and since the productivity is there, it should be half of the GDP of Tokyo. Japan is highly urban-populated. The other regions are uninhabitable or ghost rural towns. The issue is that large cities in the liberal world are population shredders.

People think the decrease in population is caused by GDP rise and urbanization -- the truth of the matter is -- that it's about the pervasive underlying ideas that spread among people that are shared across the "developed" world that causes people to change their opinion on reproduction, gender dynamics, highly self-centered and immediate, I would say hedonistic pursuit oriented that drives people toward a very shallow cost-based assessment of human life. The ego grows wider per person.

If you can imbue new values beyond those population constraints or contractions, I imagine you can maintain a large urban population with above-replacement-level fertility rates. Globalization and the diffusion of ideas become an issue as they homogenize countries with similar technological access. The education systems also feed into these layers. People underestimate how many processes in society, from how we're institutionalized and going through conditions of socialization, breed us to view life the way we do. This is why people don't make children. Many decades ago, countries had policies encouraging fewer kids to extract more productive value from each individual. All regret that policy today.

If you put in schools since elementary in how it is good to reproduce, you will see a latent effect of an increase in the fertility rate a few decades later. One needs propaganda campaigns and social awareness efforts to condition the populace that family growth is a worthwhile goal where sacrificing for that purpose is necessary and rewarding beyond financial measures. In the short-term perspective, they have to sacrifice some GDP for it, but this is a matter of long-term survival.

The thing about population implosion is that, after the economy crashes, one might see higher volatility with hardships. With the population hypothetically 20-30% of its previous size with lower life expectancy, the growth might increase rapidly again. This sounds very pessimistic and needless to say, everyone should rather avoid that, but maybe a new paradigm shift will occur after the population crumbles on itself. One can imagine a demographic bottleneck forming where new ideas form from new collective understanding with a focused common goal toward survival and not repeating the complacent attitude of issues facing society where each individual understands the problem with no one willing to give an inch to solve it. I see people have a severely childish way of thinking, believing they can "have their cake and eat it too" mindset. This is not a mental framing for survival.
