The new Truss executive in the UK is setting out to restore a little faith in conservative politics economics. First, removal of the fracking ban. Now a tax reduction package described by most commentators as the biggest cut in taxes for decades. That’s excellent news. Yes, it needs to be followed up by expenditure cuts since the real measure of tax in an economy is the level of Government expenditure rather than the tax take. But, a tax cut will help even in the absence of an expenditure cut.
The reasons are well known. Arthur Laffer is the US economist credited with the naming rights of the Laffer Curve. In simple terms, Art’s point was that at a zero rate of tax, the total tax take would be zero. Likewise for a tax rate of 100%. In other words, the tax rate that would maximize the tax take was between 0% and 100%. What’s more, at higher rates of tax, a tax rate reduction would actually increase the tax take. That can only happen if economic growth increases. President Reagan understood the concept and the Reagan tax cuts were a huge success.
Now, 40 years later, the Truss government is following the same path. Well done Liz, this is a great start.
