Where is the most expensive property in the world? For the most part, next to ports, next to railways, next to subways, next to anything that makes makes it cheap to move people and things.
Demand for housing and transport is rising beyond the means of the infrastructure to actually sustain this. Most of the whinging I see against governments surrounds their unwillingness to restrict investment and immigration, which they won’t do because their books are balanced around the notion that they will “grow out of debt”. Likely we will arrive at a point where we have a bunch of infrastructure we built that’s infeasible to maintain that will turn into ruins when the population gets around to contracting.
