Q2: Yes, obviously there is a positive correlation. This is exactly why renters need to fight: stakes are against them. Current status quo is in favor of homeowners; it will not be possible to change it while being passive. Renters and homeowners have conflict of interests, there is inevitable fight.
Q3: I think blaming is the call for fight. If renters want better deal, they need to fight. Is it most constructive? I don't know, this is the best I can come up with. Does it reinforces the status quo? No, I think inactivity reinforces it.
