We're about two years post-Wall Street reform and there have been reports that the way Wall Street does business is changing.

But a recent New York Magazine piece titled "The Emasculation of Wall Street," a study that says Wall Street is made up of people with psychopathic tendencies and Greg Smith's resignation letter makes one wonder if Wall Street has changed, will change or never change.

What does this mean for the Main Street economy and our pocketbooks?

Chris Bayer, Wall Street psychologist, will join The Daily Circuit Friday to talk about the culture of Wall Street. William Cohan, author of "Money and Power: How Goldman Sachs Came to Rule the World," will also join the discussion.
