And what do you mean by "predatory real estate owners and bankers". It's a free market system if you can't afford to live in an area then live somewhere where you can afford given what your job is. Nobody is entitled to a particular job in an area (if they are not paid enough) if they can't (with the pay) afford the rent. I'd love to live many places but I have to consider the practicality. Hawaii would be nice! [1] As far as people getting pushed out because of rents being driven up, the answer to that is not to take property away from lawful owners.
Want to "lower the rent"? Government buys at fair market value some apartments or housing how about that? (Sure that will happen, right?) Fine as long as the rightful owners agree and everyone else in the community uses their tax dollars to pay for acquiring that property.
Given you are so unhappy about this would you use your tax dollars so that others could live and not have high rent?
[1] To clarify not because of housing prices but because of economic opportunity. NYC would be nice also however housing, traffic and so on are out of my comfort zone.
