You can see from the graph that not all recessions and expansions were the same. The contraction that began in 2008 (the read dip toward the right of the graph) was especially painful compared with the eight other recessions that Americans have experienced in the past 65 years. And recessions tend to cause a lot of pain while they last: they reduce income, industrial production and retail sales, and cause rising unemployment. The stock market is especially averse to recessions; you often find bear markets associated with recessions.
