Everyone apart from the politicians and the senior echelons of the
corporations are in favour of this. It's the big corporations, namely
the banks in this case, that are being blamed for the current global
financial crisis.

Countries are reluctant to increase corporate tax because they fear
corporations won't invest in their economies. But what if it happened
across the world? This is the sort of thing that could pay for more jobs
to be created.
