There’s a significant debate now taking place in Washington – largely behind closed doors, but sometimes covered by the media – on whether fiscal conservatives should maintain a rigid no-tax-increase position. One side of the debate features Grover Norquist of Americans for Tax Reform, which is the organization that maintains the no-tax increase pledge. The other side features Senator Coburn of Oklahoma, who is part of a small group of GOP Senators who might be willing to increase the tax burden as part of a deal that supposedly reduces deficits.
I’m a huge fan of Senator Coburn, who was in favor of cutting wasteful spending before it became fashionable. His office, for instance, releases a “Pork Report” every couple of days. But you shouldn’t read it if you have high blood pressure, because it will confirm (and reconfirm, and reconfirm, ad nauseum) your worst fears about tax dollars getting wasted.
Nonetheless, I’m on Grover’s side on this tax debate for two reasons.
First, we have a spending problem, not a revenue problem or a deficit/debt problem. Red ink is undesirable, to be sure, but it is a symptom of the underlying problem of a government that is too big and spending too much.
But don’t believe me. Here is a chart from the House Budget Committee showing long-run projections for spending and revenues over the next 70 years. As you can see, the long-run fiscal shortfall is completely caused by higher spending. In other words, 100 percent of red ink is due to government spending. So why put taxes on the table?

But this chart actually understates the case against tax increases. It uses revenue numbers from the Congressional Budget Office’s “alternative” forecast, which shows taxes steady at 19.3 percent of GDP. That’s more than the historical average of about 18 percent of GDP, which surely indicates that revenues are not the problem.
However, that 19.3 percent estimate is completely artificial. As CBO states in its long-run forecast, “the alternative fiscal scenario also incorporates unspecified changes in tax law that would keep revenues constant as a share of GDP after 2020.”
I’ll actually be delighted if we can permanently keep federal revenues below 20 percent of GDP, but I’m not overly optimistic because the tax burden is projected to automatically increase over time. And I’m not talking about the expiration of the Bush tax cuts or the alternative minimum tax. Yes, those factors would push up tax revenues (at least based on static revenue estimates), but the tax burden also is expected to climb because even modest economic growth slowly but surely pushes more and more people into higher tax brackets.
