The reason, as I document in my book, "The Scandal of Money: Why Wall Street Recovers but the Economy Never Does" is that Washington and the Federal Reserve together have created a closed loop economy where the Fed creates money for the government and the S&P 500 and Main Street is left out.

The Fed decides what money is worth and who receives it and how much. The Fed prices it at zero interest rates, allegedly to stimulate economic growth. But whenever something is free, it's distributed by queue, and only the privileged, connected people in the front of the line get any, not the innovators who create growth and opportunity for Main Street. Trump voters are wrong if they blame Mexico and China, but they are right about one big thing: The economy is rigged against them.
