However, just realize this is exponential growth. You don't need a maths degree to realize that you can't keep on printing money like crazy and expect the markets to stay stable for much longer.
It takes one person to dig into the matter and ask the question: "But what covers this money?" and bang, you got a stock market crash.
And let's not call it money. What the FED "prints" is currency, sheets of paper. Money has inherent value (gold is money for instance), but not this FED-Dollar lie we live in every day. Since 1914, America has been tricked into believing into this system. When Nixon turned off the Gold standard in 1971, the entire Bretton-Woods-System (built on top of the Dollar) sort of went Berserk.
It's a system built to fail.
