The dismal unscience...

It looks like the supply-siders will be out in full force in 2008. I will admit that I don't always think economics is the appropriate field to address some questions --- at least not exclusively -- but it looks like the supply-side economic model supporters don't even think it can fathom the benefits of lower tax rates...

But advocates see broader economic benefits from lowering tax rates, which is one of the reasons the concept has reappeared as a point of contention in this year’s election campaign, in an amended form.

“What really happens is that the economy grows more vigorously when you lower tax rates,” said Kevin Hassett, an adviser to the presumptive Republican nominee, John McCain, and the director for economic policy studies at the conservative American Enterprise Institute. “It is beyond the reach of economic science to explain precisely why that happens, but it does.” [emphasis mine]

This is, of course, merely the newest argument offered up in the succession of bunk logic promoted by the "we got the cash and we're keeping it" anti-tax crowd. The best part is that you can't prove it wrong using economics, so all of those liberal economists who keep pointing out that tax revenues grew at lower rates during supply-side eras can stick it. Take that Krugman!
