Wait - how is this a tax on financial institutions/"the super rich" exactly? FTA: "The tax proposes a 0.05% levy on all financial transactions and has the potential to raise hundreds of billions yearly to support initiatives to help those most affected by the recession. In short, a 0.05% tax on the super-rich to help ease the effects of the recession on the poorest sections of society."
The banks will, of course, add at least 0.05% price changes so that their users have to pay 0.05% more. I don't see how this has anything to do with the "super rich".
