unfortunately there is no amount of wage that prevent high rent… on the contrary. All the city with low relative rend have rent control laws.

And they must be updated often since landlords try to sneak their way.

For exemple, in Paris, there is a fashion trend of building offering " coworking rent", where they rent you a 10m2 for exuberant price, and they justify it by having a "PC room " in the building or something. So the city is in the process of banning thoses “coworking” place, which are just a way to bypass rent control law
