With the unemployment rate approaching twenty percent, Mellon became one of the most "loathed leaders" in the United States, second only to Hoover himself. Facing this unprecedented economic catastrophe, Mellon urged Hoover to refrain from using the government to intervene in the depression. Mellon believed that economic recessions, such as those that had occurred in 1873 and 1907, were a necessary part of the business cycle because they purged the economy. In his memoirs, Hoover wrote that Mellon advised him to "liquidate labor, liquidate stocks, liquidate the farmers, liquidate real estate. Purge the rottenness out of the system. High costs of living and high living will come down. ... enterprising people will pick up the wrecks from less competent people."
