Also, consider this, perhaps they just wanted the homes, they did not care that they would be built in trendy Brooklyn. They just wanted something they could afford. There was always this assumption that these poor people wanted to come live in that part of Brooklyn (which I think was part of the Slopster resistance to it, but thats just me )
Rich people can be very stupid concerning this issue as well. They will settle for a short ugly building because it is contextual, but rail against a new slender building (I am think of the UES tower, not Miss Brooklyn) because it is scary and new and makes their hood look less old money.
