>Housing costs are directly related to the cost of land, which is much higher in dense urban areas. If you build up, the cost of land gets distributed over many more people. Instead the cost per unit approaches the cost of construction cost of building one more story. You don't even need super high rises to vastly increase the available housing. Even a small increase in housing would drive rent down a lot.
