Long Depression
Nobel laureate economist Milton Friedman, author of "A Monetary History of the United States", on the other hand, blamed this prolonged economic crisis on the imposition of a new gold standard, part of which he referred to by its traditional name, The Crime of 1873. This forced shift into a currency whose supply was limited by nature, unable to expand with demand, caused a series of economic and monetary contractions that plagued the entire period of the Long Depression. Murray Rothbard, in his book "History of Money and Banking of the United States", argues that the long depression was only a misunderstood recession since real wages and production were actually increasing throughout the period. Like Friedman, he attributes falling prices to the resumption of a deflationary gold standard in the U.S. after the Civil War.
Economic history of the United States
The Great Recession was a sharp decline in the United States' economy. In 2008, a series of related economic disasters hit the American and European financial systems. The bursting of a worldwide bubble in housing set the recession in motion. The end of housing bubbles in California, Florida and Arizona led to the collapse of housing prices and the shrinkage of construction sector. Millions of mortgages (averaging about $200,000 each) had been bundled into securities called collateralized debt obligations that were resold worldwide. Many banks and hedge funds had borrowed hundreds of billions of dollars to buy these securities, which were now "toxic" because their value was unknown and no one wanted to buy them.
