"Tax cuts always work."
It's more accurate to say that tax cuts work more than liberals (including our Canadian Liberals, and socialist New Democrats) believe.
Even Laffer, (he of the Laffer Curve) believes that there's a point where lower tax rates will yield lower revenues. Liberals thought the U.S. was already past that point. Apparently, you actually weren't there yet. In Canada, we're way, way above that point.

I should have added: there's no reason that taxes shouldn't be lower -- even if that actually decreasing, rather than increases government revenues. In fact, it's easy to argue that decreasing government revenues is a good thing. However, the point of this article was that revenues increased despite tax reductions -- and that sort of thing has its limits.
