The key to understanding is that a capitalist economy, while immensely dynamic and productive, is not inherently stable. At its heart is a banking system that enables large-scale borrowing and lending, without which most businesses cannot bridge the gap between incurring costs and receiving revenues and most consumers cannot achieve their desired level of consumption. When the banking system breaks down and credit consequently seizes up, economic activity plummets.


Lending borrowed capital -- the essence of banking -- is risky. That risk is amplified when interest rates are very low, as they were in the early 2000s because of a mistaken decision made by the Federal Reserve under Alan Greenspan to force interest rates down and keep them down.

The banking crash might not have occurred had banking not been progressively deregulated beginning in the 1970s.
