What are the relative merits of the different economic systems?
There are lots of different economic systems. Some of them are better than others. Capitalism is good because it encourages people to try to make money which in general will contribute lots of money towards society. However it can lead to greed and to collapses, bubbles in the market and so on – like has happened recently, so perhaps overall it is not the best system but it is the best that we have.
