It wasn't Wall Street Bankers - it was the Teachers' unions.

The looting of the U.S. and the economic crisis were not caused by Wall Street and the corporations,  it was the Teachers’ Union.

Chris Christie.

At the Republican convention.

"Now having squandered trillions on mismanaged wars, tax cuts designed especially for the rich, a gigantic real estate bubble, and massive bailouts for its banks, the United States is confronting a major fiscal problems.  At the same time, America’s fundamental economic competitiveness has declined severely, as its physical infrastructure, broad band services, educational system, workface skills, health care and energy policies have failed to keep pace with the needs of the advanced economy. ….

The principal reason for this is that politically powerful interest groups have been able to block reform: the financial services, energy, defense, telecommunications, pharmaceutical, and processed food industries, the legal, accounting, and medical professions; and to a lesser extent, several unions- these and other groups , including, of course, lobbyists and politicians, have ferociously resisted efforts to improve  America’s future at their expense.

            Meanwhile, both political parties are ignoring, lying about, and/or exploiting the country’s very real economic, social, and educational problems."
