The big elephant in the room, is those who have homes aren't ever going to let go of their homes for anything else than 100+% profit, it's in their best interest to not allow any other competition. Neighborhoods that argue over inches of fences and HOA colors, routinely come together to block apartments and other housing.

This holiday season, family members will be openly bragging about how their home is worth 1.7 million, which they purchased for 300k. The room full of apartment/roommate living student debt loaded will get very quiet.
