I’ve argued, ad nauseam, that the single most important goal of fiscal policy is (or should be) to make sure the private sector grows faster than the government. This “golden rule” is the best way of enabling growth and avoiding fiscal crises, and I’ve cited nations that have made progress by restraining government spending.

But what’s the best way of actually imposing such a rule, particularly since politicians like using taxpayer money as a slush fund?

Well, the Swiss voters took matters into their own hands, as I describe in today’s Wall Street Journal.

Americans looking for a way to tame government profligacy should look to Switzerland. In 2001, 85% of its voters approved an initiative that effectively requires its central government spending to grow no faster than trendline revenue. The reform, called a “debt brake” in Switzerland, has been very successful. Before the law went into effect in 2003, government spending was expanding by an average of 4.3% per year. Since then it’s increased by only 2.6% annually.

So how does this system work?

Switzerland’s debt brake limits spending growth to average revenue increases over a multiyear period (as calculated by the Swiss Federal Department of Finance). This feature appeals to Keynesians, who like deficit spending when the economy stumbles and tax revenues dip. But it appeals to proponents of good fiscal policy, because politicians aren’t able to boost spending when the economy is doing well and the Treasury is flush with cash. Equally important, it is very difficult for politicians to increase the spending cap by raising taxes. Maximum rates for most national taxes in Switzerland are constitutionally set (such as by an 11.5% income tax, an 8% value-added tax and an 8.5% corporate tax). The rates can only be changed by a double-majority referendum, which means a majority of voters in a majority of cantons would have to agree.

In other words, the debt brake isn’t a de jure spending cap, but it is a de facto spending cap. And capping the growth of spending (which is the underlying disease) is the best way of controlling red ink (the symptom of excessive government).
