Removing restrictions on building would go a long way towards solving the problem IMO. You'd get uglier cities maybe, with taller buildings in more expensive areas, less parks, etc., but you'd get cities where more people could live, in terms of the amount of apartments per square mile as well as price (as the two ought to go hand in hand at least somewhat.) I think that today's restrictions on building in many places are absolutely draconian, to the point of a chronic shortfall in the number of apartments built not just in city centers but in entire cities. I think that to some extent this is explained by a collusion of builders, property owners and bribed government officials (so corruption), and to some extent it's explained by the government liking to restrict building to preserve open space or what-not and not liking to do the work needed to plan and execute urban expansion at a decent rate (so laziness).
