The story in Sweden was similar. During the era where Sweden was more heavy into social democracy and the government doing things itself, they had the "million program" where they built a million homes in 10 years (this was when the population was like 7 million). But since the 90's the name of the game has been market economy and privatization and the government doesn't get involved as much (aside from the underfunded local government housing companies). And now those million homes are poorly maintained and decrepit and need to be replaced and nobody is picking up the tab.
