[the urban politician]

So in other words, private property owners will be forced to sell only to the Government and nobody else?

How are these properties appraised? They are appraised by what the Government is "willing" to pay for these properties. And the Government can simply keep the cost to acquire these very low by 1) making low offers, and 2) hang the stigma of low income housing over these districts.

A very bad, abusive precedent. Worse idea ever. Luckily it's happening in France and not over here. I'm fed up with the Government trying to "solve" the affordable housing issue when, in reality, the free market can easily solve this problem without Government interference.
