Why we need some greed....

Capitalism has had a bad press over the last few days - "greedy" bankers screwing up the economy, the mysteries of short selling have be explained God knows how many times to a bewildered public who haven't a clue as to what is going on except that it is bad and are looking inwards at jobs, prosperity etc

But some greed is a must since it drives forwards the economy and it provides us all with a increased standard of living. As a colleague put it nicely today: "If we were all tolerant, caring, sharing people, we'd all still be being very nice to each other living in our mud huts."
