Restricting supply obviously increases prices. That's economics 101. Their claim is that they are doing it precisely for economic gains. Whereas I'm saying that it is actually not about the economic gains because they are giving up economic value (much higher land value) in order to preserve non-economic things (neighborhood, view, etc.). My point is that an acre of land in the center of Manhattan is worth a lot of money. That value goes drastically down if something prevents you from building above 35 feet.
