In a letter to this week's Economist, one of the leaders of the Occupy Movement stated that they are not anti-capitalist - they are just opposed to an unjust society where the 99% bail out the financiers and banks who have created a huge economic mess. We were all told the lie that the bailout was necessary to prevent economic meltdown. Despite all the bailouts, we still have economic mess and ordinary people are feeling the economic pain of having bailed out the financial system through falling real pay (if they are still in a job!) and reduced provision of public services. This is why we have the Occupy movement.
