Earlier quoted context omitted.
Nobody is entitled to live in posh neighborhoods. That is a false argument.
You don't see any reason why it might be worse for someone who lives in an area, and already has a life there, to be kicked out, than it would be for someone else not to be able to move in?
The biggest bargaining chip a renter has is the ability to leave. If the housing market is functioning correctly then renters should have the upper hand and these issues don't matter.
Nobody is "kicked" out because nobody has an intrinsic right to live in a particular neighborhood. Arguing such a thing is in complete opposition to a free market.
