Okay, the quote is from a comment posted today on the In Shaw Blog.
"If you're forced out, you just have to deal. There're plenty of affordable areas just a couple of miles away anyway. What's the problem with that?"
There are lots of problems with that. First, affordable areas aren't always "just a couple of miles away". The individual or family that's forced out may end up a good distance from their original home. Second, residents who are forced out aren't just leaving their home. They're leaving everything that makes up the fabric of that community: from the friends and neighbors they socialized with to the schools, classmates, and teachers their children cared about. Finally, the community loses whatever the residents contributed. Things that newer residents may or may not provide.
Yes, neighborhoods change. It's part of the cycle that cities go through. City dwellers have to accept that part of urban living. These changes usually bring both good and bad. When the people who kept the community going during less prosperous times are priced out, that's definitely bad.
