Apparently, The Robin Hood Tax is justice because the money will be used for good deeds.
Don't believe this crap because the whole thing is a big con. This talk about the banks paying their fair share is a distraction from the fact the government had a hand in mess when they propped up their cronies in the financial sector. Instead of letting the insolvent banks fail, they endorsed the swindlers' actions by giving them tax-payers' money. Now they want to claw some of that money back in the form of taxes to fund their "good deeds". Of course, the government will get a nice slice of that pie too.
The banks will just pass the costs on to their customers so, as usual, we'll end up footing the bill.
