One thing to remember is some of the wealthiest people in the twentieth century made their money during the great depression. 

In the twentieth century, schooling became a social tool for an industrialized society or, worse, a perceived panacea for social injustice, crime, and poverty.

Indeed, the Federal Reserve adopted various different measurements of the money supply throughout the second half of the twentieth century and dug deeper and deeper into balance sheets in an effort to track the creation and circulation of what are known as "eurodollars" in an effort to determine how much money should be in the economy.
