I meant this one
But I agree, we should stop here.
Productivity has nothing to do with the real estate. There are more people on earth and, I don’t have numbers at hand, but from what I remember, the lodging area occupied per person keeps increasing and increasing.
(Did we have this discussion few years ago already?).
Even during the last 50 years or so; in 19th - early 20th century it was rather common in cities that a multigenerational family would occupy one room. So we can say that unlike all other resources, living space is getting less and less available. So you shouldn’t be surprised that our Lord the Market makes it expensive!
Of course there are areas with a huge demand and those with a moderate one. Even in Switzerland, you can buy or rent lodging at very affordable prices in small villages of Canton Jura. But that’s not what you are looking at.
