Yes there is a big differenxe between a rich and poor and there exist a class in between called the "middle class" who were struggling hard either to reach upward and doesn't get slide down.
This class doesn't have to loose much and enjoy the life most however the greed to earn more may put them at risk of losing everything...these class constitutes of working class and small business owner......anyway that building were crumbling from outside, and with the amount of noise coming from it, I think it was ok from inside . Many people were living inside...and they were happily enjoying the rain dance.
