When I hear this, I hear jobs and the most revolutionary green company are not welcome. If that's the case, Berlin is lost.
There is good and bad to gentrification. You don't hear stories of the people who bought their house for 50k in 1980 who then sold it in 2010 for 1.3MM. Or the people thankful they don't have to walk around in fear of gangs for themselves or their children.
TO me the biggest problem is the State. In SF, among many many other things, it's their zoning policies that caused the housing crisis. But they run education and media. So people blame the most revolutionary green company, or others bring wealth to the area, instead of the State.
