There are a lot of positive things that can be accurately said about the economy, and a lot of points in favor of the corporate tax-rate reduction that was the centerpiece of last December’s Republican tax bill.

As Marc Goldwein explains, though, what can’t reasonably be maintained is that the reduction in corporate tax rates is raising revenue. That’s ok! It doesn’t have to be adding revenue to be a good idea. But the likelihood that it’s losing revenue suggests it would be an even better idea if it were coupled with spending reductions or more downsizing of unjustified tax breaks. It also suggests that people who favor the tax bill should drop this claim.
