It's all done by computer. It's electronic money. It's also known as rearranging deck chairs on the Titanic.
From USNews.com:
One possible option the Fed has is another round of quantitative easing, a process in which the government purchases assets from banks and private companies in order to add a set amount of money into the economy.
Often confused with printing money, quantitative easing uses the new electronically-created cash to purchase government bonds and other assets, rather than using newly minted money to pay off government debt. The U.S. government began its first round of easing in November of 2008, followed by a second round in November of 2010. For the past several years the Federal Reserve has also maintained interest rates near zero, in attempt to boost economic recovery after the 2008 recession and housing market collapse.
