Ooh my first mention!

I’m not familiar with Brazil’s housing situation specifically but building more affordable homes and increasing social housing stock would increase the supply and reduce prices.

Definitely feel you on the lack of jobs locally. Its going to take provincial or national planning and investment to fix.

Sounds like a major enough city, I think most major European cities with subways usually have multiple crossing lines and a decent bus network to fill the gaps. Interestingly I don’t even think that’s the weirdest metro layout, personally I have to give it to Glasgow. They have a single subway loop that runs 2 directions and its the 3rd oldest underground rail transit system but it hasn’t had the route changed or expanded in 125 years. They do have an advantage of having a decent bus system though.
