People move to where there is jobs and money. You can't build the housing first, in our society you need capitalists to invest into building businesses to make people want to move there. And because we have spent decades killing small business in favor of corporations, you need corporations to decide to build where there are no people and they have to pay a small short term premium to attract workers. Except corporations don't like doing that because it is a longer term investment and they are worried about next quarter's numbers and maximizing executive level bonuses which means short term planning.
