In order to keep housing affordable, the state must intervene. Likewise, wages must increase massively, at least 3 to 5 percent annually.

But I do not see that at all at the moment.

How should the state intervene here? Just because it supposedly subsidizes housing, they wouldn't be any cheaper, someone else just pays (along) for it.

And the state can't raise wages twice over except for its own people - by voluntarily exceeding the union demands ;) Otherwise, collective bargaining autonomy applies.

When wages rise, prices and costs also rise again. A constant cycle ...
