According to the Guardian:
Britain should raise income taxes by 6p in the pound to make bigger inroads into its huge deficit or risk being vulnerable to the next financial crisis, according to a leading thinktank that advises the Treasury.
Current plans by the political parties to reduce spending and pay down debt would not be enough to prepare the country for a collapse like that of Lehman Brothers and a deep recession, said the National Institute of Economic and Social Research (NIESR).
The hard-hitting criticism of plans by all political parties to cut the deficit, and especially the reliance on "mythical" efficiency savings, came as Europe was convulsed for a second day by the aftershocks of Standard & Poor's decision to downgrade Spanish government debt.
They're right on cuts and savings: they're just not going to happen.
6p tax change would increase revenue by up to £30 bn.
It's going to happen.
But this is not the best way.
That's explained in The Great Tax Parachute.
