Tbf, the problem comes in when developers (or someone - developers are probably just the most visible) make a pile of cash for coming in, pushing renters out of a small numbed of relatively affordable units, ploping down a building with a large number of completely in affordable units, and causing a huge headache for everyone living in the area in the process.

I'm generally for development, but the way it's carried out in many cases tends to screw over existing residents while benefitting mostly just people-who-dont-live-there.
