When I read in my local paper, the Sun Gazette (published in Washington’s Virginia suburbs), that the Arlington County Board was planning to raise property taxes, I prepared the chart below. It shows how my own property taxes have risen since I bought a house in 1997 (with my first tax bill, in 1998, set at 100). I had the following letter published this week in the Sun Gazette: 

[Arlington] County Board members are discussing raising the real estate tax rate by 5 cents. The Sun Gazette on Feb. 28 published a chart showing that the proposed rate was actually higher in 2000 and 2001. But what you didn’t show was the soaring level of real estate assessments. Property taxes are much higher than they were a decade ago. My first Arlington tax bill was in 1998. My 2012 bill was more than double the 1998 rate–about a 127-percent increase. I think that’s true for most Arlington homeowners. It’s not easy to find past budgets on the county government’s Web site, but I would assume that the county’s revenue has gone up approximately as much. So Arlington isn’t hurting for revenue; it’s just itching to raise spending even faster than tax revenue rises. The Sun Gazette quoted County Board member Libby Garvey saying that a 5-cent tax hike is “a very good compromise.” Not for taxpayers, it isn’t.

This pattern happens in many states and localities, of course: they spend money freely in good times, then run into trouble when the economy or the housing boom slows down. As Chris Edwards told a reporter in 2009, states during the preceding years had “repeated the same mistakes they made in the late ’90s, assuming the good times were going to last forever.” And when the money stops rolling in, they don’t want to cut back–so they decide to raise taxes to keep their revenue and spending at the high levels they reached during the boom.

Back in 2010, I wrote a post entitled “What’s the Ideal Point on the Laffer Curve?”

Except I didn’t answer my own question. I simply pointed out that revenue maximization was not the ideal outcome.

I explained that policy makers instead should seek to maximize prosperity, and that this implied a much lower tax rate.

But what is that tax rate, several people have inquired?

The simple answer is that the tax rate should be set to finance the legitimate functions of government.

But that leads to an obvious follow-up question. What are those legitimate functions?

According to my anarcho-capitalist friends, there’s no need for any public sector. Even national defense and courts can be shifted to the private sector.

In that case, the “right” tax rate obviously is zero.

But what if you’re a squishy, middle-of-the-road moderate like me, and you’re willing to go along with the limited central government envisioned by America’s Founding Fathers?

That system operated very well for about 150 years and the federal government consumed, on average, only about 3 percent of economic output. And even if you include state and local governments, overall government spending was still less than 10 percent of GDP.

Moreover, for much of that time, America prospered with no income tax.

But this doesn’t mean there was no tax burden. There were federal excise taxes and import taxes, so if the horizontal axis of the Laffer Curve measured “Taxes as a Share of GDP,” then you would be above zero.

Or you could envision a world where those taxes were eliminated and replaced by a flat tax or national sales tax with a very low rate. Perhaps about 5 percent.

So I’m going to pick that number as my “ideal” tax rate, even though I know that 5 percent is just a rough guess.

For more information about the growth-maximizing size of government, watch this video on the Rahn Curve.

There are two key things to understand about my discussion of the Rahn Curve.

First, I assume in the video that the private sector can’t provide core public goods, so the discussion beginning about 0:33 will irk the anarcho-capitalists. I realize I’m making a blunt assumption, but I try to keep my videos from getting too long and I didn’t want to distract people by getting into issues such as whether things like national defense can be privatized.

Second, you’ll notice around 3:20 of the video that I explain why I think the academic research overstates the growth-maximizing size of government. Practically speaking, this seems irrelevant since the burden of government spending in almost all nations is well above 20 percent-25 percent of GDP.

But I hold out hope that we’ll be able to reform entitlements and take other steps to reduce the size and scope of government. And if that means total government spending drops to 20 percent-25 percent of GDP, I don’t want that to be the stopping point.

At the very least, we should shrink the size of the state back to 10 percent of economic output.

And if we ever get that low, then we can have a fun discussion with the anarcho-capitalists on what else we can privatize.

P.S. If a nation obeys Mitchell’s Golden Rule for a long enough period of time, government spending as a share of GDP asymptotically will approach zero. So perhaps there comes a time where my rule can be relaxed and replaced with something akin to the Swiss debt brake, which allows for the possibility of government growing at the same rate as GDP.

The latest report by the Washington Post’s David Fahrenthold on Beltway tomfoolery tells of what happened when both Democrats and Republicans asked government workers and the public for suggestions on how to reduce government spending. Apparently neither party had much interest in the responses.

Fahrenthold first looks at the Obama White House’s effort:

After President Obama set up a national online suggestion box asking federal workers for new ways to cut the budget, 86,000 ideas came in Some, inevitably, were a little odd. 

…But many others were more serious, sent in by people who had seen real government waste close up: stop the “use it or lose it” budgeting policy, which leads agencies to blow taxpayer money at year’s end; stop giving paper calendars to workers who already have online calendars; stop letting every armed service design its own camouflage. 

In the end, none of those things happened. Instead, those suggestions became a little-known part of the maddening story of Washington’s budget wars. 

…Obama, for instance, chose 67 suggestions out of those 86,000. While some produced results, many seemed unambitious. Often, the administration picked ideas that applauded what it was already doing, instead of forcing it to start new reforms. Still, the White House considers that a win. 

Of course it does. 

Fahrenthold then turns his attention to the GOP’s “YouCut” website. Created in 2010 and run by House Majority Leader Eric Cantor, regular Americans were to be given menus of potential spending cuts, and they were asked to vote for one. Winning ideas were then supposed to go to the House floor for a vote. In the end, only two of the 36 winning ideas became law. No bill was introduced for nine of the winning ideas, and 12 were “introduced only,” which means that they never even made it to the floor for a vote.
