Like gold, U.S. dollars have value only to the extent that they are strictly limited in supply. But the U.S. government has a technology, called a printing press (or, today, its electronic equivalent), that allows it to produce as many U.S. dollars as it wishes at essentially no cost. By increasing the number of U.S. dollars in circulation, or even by credibly threatening to do so, the U.S. government can also reduce the value of a dollar in terms of goods and services, which is equivalent to raising the prices in dollars of those goods and services.

Importantly, in the 1930s, in the Great Depression, the Federal Reserve, despite its mandate, was quite passive and, as a result, financial crisis became very severe, lasted essentially from 1929 to 1933.

Not all information is beneficial.
