I have lived in areas that were gentrifying. Everyone knew that rents were going up and would continue to go up, but few were willing to leave. People with small nest eggs preferred to blow it on higher rents than invest it in relocation. The general attitude I saw was 'I have a right to live here so I will, even if I can no longer afford it.'

Not only that but people have an emotional investment; "This is my home", "All my family lives here", "It's all I've ever known", etc. Moving to someplace cheaper may not be an improvement overall. Financially maybe, but what's that worth if all your friends live across the state, or you can't just hop into a nearby pub (if that's your thing) like you used to, or you have to drive for an hour to get to work instead of a 15 minute bike ride?
