Many people would be by the amount of money they have. Personally I've always wanted to know who is making how many long distance calls for personal fun at the kh because the accounts reports never were the same. And how is it that the building has higher utilities than my house though its not occupied as much and is virtually the same size.
One recent thing recently is in Brooklyn the Society won the right to rezone certain buildings. It of course increases thier dollar value should they decide to sell.
