This will not help. You are supposing that the people who feel disenfranchised in the Rust Belt want to move to NYC where they can get cheap housing and work in the city. They don't want the China model of having a Foxconn that hires rural workers to work in the big city.
What these people want isn't fully rational; it's highly emotional. They want their 1950s-style old way of life back. They want their jobs in their towns that they grew up in, that they have lived in or raised families in, where they have their church and their community. They want to live in their IL farm town and work at the local union plant and make a living to pay for pensions and healthcare. It is not realistic in a globalized economy and will be less so in a fully domesticated one, but the math is not what matters here.
Urban areas in these places already have plenty of housing that nobody is in. See Detroit for example.
