UPDATE: Today a group of protesters known as Occupy Wall Street[Link] frustrated with the workings of the current financial system protests in USA. One commenter wrote that the video unfairly vilifies banks and bankers when they play an important role in the economy. While that is true, the video warns us not to fall into the trap of de-regulation and always monitor and regulate our financial institutions strictly. When Franklin D. Roosevelt spoke during his inauguration speech[Link] after the stock market crash of 1929 and the subsequent economic depression, he warned of bankers and their system and how it led to despair in the 1930s - the greed will do us in. 70 years later look around you in the past 4 years - Goldman Sachs,, Lehman Brothers,, the sub prime crisis, the sovereign debt crisis - which one is not caused by debt...and money is indeed debt.
When you go out to buy your next television set, it is likely that you end up with something better than your existing TV sold for the same price. Like many things around us, man made systems tend to improve over time - if you take Boeing's newest aircraft, The Dreamliner, you will expect that to be build with more safety features than the old Boeing 747.
There is however one exception, our financial system - it seems to get less stable with each passing year and generates crisis, turmoil and recessions much more often that in the past yet we seem to accept this all encompassing system because most of us are born into or do not really understand what goes on in the banking system. Here is an interesting video that explains quite clear how money is created, how it drives the economy and why we are seeing so many crisis and so much in stability in the current system.
