The amount of new apts would be dramatically high to curb prices and make them realistic again. And Berlin is probably also not able to magically create as much new living space as is needed in that short of a time frame especially given the developers unwillingness to build affordable housing. I think where we probably fundamentally don't agree is that not all things need to be provided through a market. (or I think my point is more so that we've at least observed it not reall working here, so we could at least try a different strategy or multitudes and see how far those take us)
