Urbanization Has Only Two Directions
One is centralized urbanization, or the siphon effect of large cities.
The other is urbanization as a process of decentralization and fragmentation.
Looking at the current global reality, virtually every country is centralized. In Japan, one-third of the population lives in Tokyo. Put simply, anyone with a clear head can see that those who have made money have already bought up properties all over major cities.
Anyone who can make it to the city has already done so. Those who haven't been able to move to cities over the past few decades are generally people with weaker earning ability relative to the village population.
If you want to invest in county-level cities, what conditions would need to be met to suddenly make these relatively low-earning people much more productive? Only by resolving these conditions can the next wave of economic growth be triggered—that is where the real opportunity lies.
