The GP is talking about the biggest problem that America has now: people can't afford homes. The article it trying to hook the reader by promising to tell them about this problem. What follows is implicitly delivered as a solution to this problem. GP is correctly pointing out that it's not a solution. They are further lamenting that the current solutions to the problem (earn little of commute a lot) are sub-optimal. The Gates foundation is doing something, kudos to them, but they are unlikely to make a dent in solving this problem.
