Buy more land and more property. Rinse repeat.

This has been my exact experience in Manhattan, where a 3 Bed apartment got converted into 5 Bed. After we refused to pay additional rent. Interestingly in Mumbai my apartment building (a Co-op where we own) decided to demolish / rebuild and reduce the playground associated with the building. This allowed us to raze the 6 storey building built in 1960 into a 12 storied one. As a result, we now have an apartment in the same co-op with equivalent sq. footage and were paid additional money plus rent while the building was being rebuilt. Since it was a Co-op we could shop around for a developer who offered us the best deal. The current building will at least sustain till another 50 years. I have never found this happening in US. Since either the building did not have enough free space to expand upon adjacent to them or restriction on height increase.
Unless you own a significant fraction of the market, you'd make way more developing the second property than sitting on it.
I mean in London you need a special mortgage when buying new build housing because usually the price you pay is far in excess of the market value - you can literally make a 20% loss if you sold it in the first year or two! Of course as we all know housing always goes up in value and that's built in to the price!!
It feels as though you could build a huge number of houses in London but it never comes close to matching the required supply. In every other industry you would assume everyone should have a car and everyone should have a tv or computer, but within reason, everyone who wants to should be able to live in New York or London? We think that is insane.
Point out to them that poorer people around the world are experiencing an incline in living standards, so they should be thankful for the opportunity to work for less and less since there's still someone worse off!
>>> This ignores basic economic realities
Maybe you can see a time where in San Fran or New York or London there will be enough housing built to simply maintain the current price? I can't though...
