Who do you mean by "you", when you say "you should"? Do you mean you as in YOU? Or everyone else? Of course people who can't afford housing want cheaper housing. But people who have housing don't want high-rise buildings in their neighborhoods and that's understandable. The solution is not to build more housing. The solution is to create work in other places, too. Why should all companies be in SF? Force companies to move to states with plenty of space.
