Earlier quoted context omitted.
If the city wants something the market can't provide the solution is to do it yourself. Berlin is partially doing that. The "Wohnungsbaugesellschaft Berlin-Mitte" is a housing association owned by the City of Berlin that builds and rents out apartments. They more or less act like other investors, just with more focus on social factors than on high profits.
> just with more focus on social factors than on high profits Which is basically a political issue, because they will say "some people are more equal than others". Personally, I prefer naked capitalism over this "you need to know somebody in the party to get a good flat"-stuff.
Here in Stockholm a lot of the public good properties have been sold out which have left precious little for too many to contend.
Prices of labour and land are so expensive that, allegedly, profit margins are not good enough.
The "know somebody" bit goes for plain hard capitalism as well, but is less in effect in a society that actually focus on the social side of things. IMO.
