In the interest of keeping this going till the 5k mark..
Look, money=scam. 95% of all money in the world right now is digital debt, backed by government bonds, held up by... kiss and promise? The Greek crisis is the prime example, the vast majority of the money in that debacle has nothing to do with Greece itself but with the currency exchange leveraging in Europe.
Yeah, total world debt amounts to about 200 trillion dollars which equals about three times the annual turnover of the planet. And this bankrupt system "insures" itself with derivatives and swaps (basically insurance contracts) amounting to many times that debt. Some say it´s 700 trillion, others 1.5 Quadrillion, nobody seems to know for sure. It sure looks like a ponzi and one that has been going for quite a while. I guess it´ll collapse when enough number of people lose confidence in it.
