This article says the super rich are panicked and are building bolt holes where they can go to hide from the revolution that will come here in America. They are worried about income equality and they are afraid they make and own too much.
Most of the income equality stuff is just looking at what has always been and making it a big deal. "Poor" people in America have running water, flush toilets, cable TV, flat sceen TVs, cars, electricity, health care, Obama phones, $200 sneakers, free education, etc. Things the middle class don't have in most of the world. Rich people have always had multiple homes, all over the world. There is always the possibility of war, earthquake, famine, flood, revolution.
If the super rich were so concerned they could give away large amounts of their fortunes. They could cut the costs of the products, goods and services they provide. They could do any number of high profile things to prevent this revolution if they really thought it was coming. I think we are a long way from revolution; that's the view from the Hysterical Right Wing.
