First there was this report, now this. I wonder what Romney, conservatives, et al will say about this…

According to a new study by the Congressional Research Service (non-partisan), there’s no evidence that tax cuts spur growth. In fact, although correlation is not causation, when you compare economic growth in periods with declining tax rates versus periods with high tax rates, there seems to be evidence that tax cuts might hurt growth. But we’ll leave that possibility for another day.

One thing that tax cuts do unequivocally do–at least tax cuts for the highest earners–is increase economic inequality. Given that economic inequality is one of the biggest problems we face in this country right now, this conclusion is very important.
