I used to live in South America (mid-tier city), living here in Berlin my will never understand how such intelligent people in general (no irony or sarcasm) never thought in a collective sense that if you have a market with a rigid supply in terms of availability (not occupied homes with no incentives for renting), it never made a serious planning for building.

I was travelling to some big cities (between 70% of size of Berlin to 4x its size) and you can find a plethora of options since something modest that can fit in a minimal income (salario minimo) to nice appartments.

Here we had in the last 7 years 55K units made, but in my home city alone we had more than 470K in a single city; if you're willing to be 1 hour away by car you can find apartments that the normal berliner never would have access in his/her entire life.

Not to dunk on berliners, but once you're in the environment where people do real housing at scale you will see a small magic in terms of prices for the legacy supply dropping.
