This criticism of gentrification ignores the sellers who are glad to take the money for what they invested, and the reason the industry moved to that area in the first place was to get access to the people who were there. The landowners
are the community, provided that they are present and managing their investment. This is a fundamental cognitive divide as well, as the positions aren't reconcilable because it's a chicken/egg problem. One is as good a metaphor for either as the other.
I may even have a proof that people mostly migrate to where they can find stability, and away from where there is uncertainty and volatility. Long term residents are the stability.
When there is an imbalance between the sides, it needs correction, and advocating for the people who actually build these desirable streets and neighbourhoods that are so attractive for others to come to seems like the braver cause these days.
