QotD: Falling down the wrong side of the Laffer Curve

David Cameron, Tory leader, appears determined that it will not be just the current government that comes out with serious errors on policy. This refusal to not state that a new, higher tax band of 45 per cent "on the rich" will be repealed is a serious error. The error is to ignore the history of what happens when marginal tax rates are cut — these cuts lead to more, not less, revenue. Now of course, as small-government folk, we support tax cuts because we want taxes to fall, and not because we want higher revenues. But if it is revenues you are worried about, then raising taxes is dumb.

The UK and many other economies are falling down the wrong side of the Laffer Curve. It is profoundly depressing that the lessons I thought had been learned have been so totally lost. It makes me wonder whether any senior politician has a clue about economics whatever.
