 "[The graph] displays the relative wage in finance in the Tri-State Area (New York, New Jersey, and Connecticut), where “Wall Street” employees are likely to generate income, together with the relative wage of finance in the rest of the United States."

After deregulation began in the 1970s, Wall Street pay levels took off. Greed is not good for the rest of us, as the ICT bubble, the housing bubble, the financial crisis and the Great Recession have shown.

By the way, the tax laws also say that the Wall Street guys get to keep more of the money that they get than the rest of us do the money we get!
