I was just thinking about this today... I was thinking with the ponzi scam where you tell the investors that their investments are worth x, while in reality they are worth x - y. The way that the ponzi scam continues is if more and more investors continue to invest paying off the ones who are want to cash out. The ponzi scam will fail if a certain amount want to cash out > the value held in the accounts. Then I thought about the US goverment, isn't this the biggest ponzi scam ever? They are 12 trillion in debt, have another 40 something trillion in libalities (Social security & medicare / medicade when the bommers die off). not to mention the US has a negative cash flow of 500 billion each year. Eventually there isn't going to be enough people who are willing to invest to keep this ponzi thing going. SCARY!
