>It's 2016, and people still think that if someone moves into your neighborhood, someone else has to move out. How does this work in your head? When the new homes are being built, where do the people who were living on the land they're being built on go?
They go into higher-density buildings, just like everybody else. That, or nothing changes and they get priced out. Those are the options.
A 500k house never gets torn down to become 3 400k condos. It becomes 3 600-800+k condos.
We should build more, because we need it. But "build more" can't be the only tool to lower prices, because simple observation shows us that it doesn't work.
