If there is lots of housing in places where there used to be good jobs then there isn't a lot of housing because for practical purposes. It's the same as replying to the issue of poverty with there are N good jobs unfilled when N is some small fraction of the number of people in poverty. It's trivially true that some can and in fact will climb out of poverty by accepting those N jobs and simultaneously true that most can't climb out of poverty via those jobs alone because multiple people can't accept the same position. Most of the people who are on the edge of not being able to afford <insert city here> can't all move away into the suburbs let alone Detroit because they can't earn enough money for all the things that aren't cheaper and it would cease to be cheaper as soon as collectively chose to do so. It is only cheap because its undesirable.
