Part I: How We Got Here:
The Reagan Administration of the United States began a thirty-year-period of deregulation by the legislators in the financial system. Deregulation allowed the financial sector more freedom and less discipline, which provided more opportunity for profit and risk.

The system developed is named the Securitization Food Chain. Simply stated, the Securitization Chain is a system whereby borrowers receive home loans from lenders and the lenders pass these loans across a chain of investment banks, investors, and the insurance company AIG. With each trade, one party earns a profit and the other party earns the loan.

The result was the opportunity for virtually anyone in the US to receive a home loan and purchase a home, which sent home prices incredibly
