The documentary Inside Job examines the 2008 financial crisis. It analyzes the changes in the financial industry that led to the crisis, including political moves toward deregulation. This allowed large risks to be taken and regulations to be circumvented. The crisis began with rampant lending and investing on Wall Street. Banks financed subprime mortgages and mortgage-backed securities became very profitable. However, the housing prices were inflated in a bubble that eventually burst in 2006-2007 when homeowners began defaulting on loans. Despite signs of growing risks, regulators refused to intervene and the financial system crisis ensued in 2008.
