"I could come up with a pretty good list of tax rate cuts financed by spending cuts that would increase economic growth."

A very succinct and potent discussion of the connection between cutting taxes and economic growth by Gerald Prante on the Tax Policy Blog:

"If Bernstein's standard for "high" economic growth is that a tax cut pay for itself, I would agree that no major tax rate cut at today's tax levels is going to promote that much of economic growth. (I'm referring to major federal taxes, as I'm sure there is somewhere out there in a state that lower tax rates would pay for itself...say on a cigarette tax or something where there is huge border activity. Also if you consider certain prohibitions to be implicit taxes, repealing them and in effect cutting tax rates would pay for themselves.)

But Bernstein's position seems to be like many on the left, which is a lexicographic preference for government always getting bigger, and he's trying to act as if it's a free lunch. It's very similar to the view of those on the right who say that government is a waste and should be starved of all revenue. The fact of the matter is that the optimal size of government > 0, but it's optimal size is not 100 percent of the economy (and there would be substantially lower economic growth if that was the case).

There are some government spending items currently in existence that are not worth their costs to taxpayers. Then again, there are some hypothetical government spending items that do not exists right now that would be worth additional tax dollars. The secret is finding which spending items are worth their costs and only funding those, and raising the necessary revenue in the best possible way that meets various criteria (such as equity and efficiency).

It is one of the paradoxes for those who seek to rally support for starving the beast (even if it worked say at the state level under a balanced budget rule). You are starving a beast because you view the beast as too wasteful and not looking out for the best interest of the taxpayer. But whose to say that when you starve it, it's going to devote its now more limited resources to the best interest of the taxpayers. It may starve you in return of the services you and those who you seek to garner support from value most (since you already believe that it doesn't look out for your own interests), thereby not getting rid of the programs at the margin that aren't worth their costs to taxpayers but instead getting rid of the programs that are worth their costs."

Any tax must be looked at and judged by the conditions of the economy, what the money is needed for, the level of debt, etc. Even if you believe in limited government, there is no getting away from analyzing the effects of particular taxes and whether or not they are worth it, even to you. In our complicated economy, it's a hellishly hard thing to do, but there's no way around it. There's not even an easy way to judge simplifying taxes or tax rates, without discussing what you need the money for, and whether the simplification gets you to where you want to go.

Any tax or government expenditure needs to be examined on its own.
