Bigger only makes the rich richer, big banks do not support or enhance the common good. Break up big banks and break up Wall Street. But chances of that happening when we are an oligarchy are a billion to one. We have created a society where greed is a sought after value, and nothing demonstrates that more clearly than big banks, big business, and big government that is controlled by money, greed, and power. It serves the top 1% of the top 1% well, and leaves the vast majority of people in less than desirable conditions.
