But that’s not the reason for expensive rents in big cities.
It’s because many (rich) people want to live there … and due to physical and regulatory limits you can’t build more housing, even for piles of money it would be worth.
Biggest pain point in housing is the limited amounts of land and living space, not the building cost.
> what do you expect your government to do?
There are tonnes of things governments can do:
1. build more dense public housing
2. ban Airbnbs
3. ban private equity from turning the housing market in their private casino table
4. tax the hell out of empty apartments and poorly utilized land that's not for living or relevant economic productivity
5. incentivize remote work for white collar jobs so they don't all have to live in X city just to do things that could be done from anywhere else
Build public housing and only charge a reasonable fee for it.
I don’t know if at the time people protested against the foul smell of the Chicago river. But the government reversed its course to improve the life of its citizens.
Why shouldn’t governments similarly deal with the housing issue using the means they have at their disposal?
(in both cases: the construction of public infrastructure)
By ingreasing taxes it can make the private sector less competitive and redirect virtually all resources on public projects.
In capitalists states you could even argue that this is the only role of the state. Detecting failures in the market, first trying to fix them by light interventions, like law changes or incentives and if still not successful fixing them directly.
