The prime opponents to new housing construction aren't people who complain about gentrification or luxury housing. Those groups don't have that much political power. The proof for this lies in the fact that most new housing construction in American cities takes place in lower to middle income neighborhoods.
The opponents to transit and living construction tend to be people who complain about "other people" moving in, "my property values", and "neighborhood character".
We are on the same side of this issue, I simply urge you to direct your anger at more appropriate targets :)
