The reason I say that is because of https://en.wikipedia.org/wiki/Induced_demand NYC built all the housing they possibly can, and yet I personally still could never afford to own property there. Same with LA.
I'm also opposed to the building of more roads. Not because (as you might claim) I own existing roads and have a vested interest, but because I know that more roads simply means more traffic. The places that have the most roads also have the worst traffic.
I wish it were different.
Nevertheless, I completely hope that I'm totally wrong on everything I said. It would mean that I might finally be able to afford to buy a house in those places.
