Liz Truss’s Tax-Cut Plan Meets the Big-Government Ratchet

In economic terms, it has ensured that in almost all advanced economies, the state grows ever larger. Once a certain level of taxes, benefits and other spending is set, it is almost impossible to reduce it. The constituencies that benefit from the expanding fiscal largess are always louder than those who don’t. The inexorable logic of self-aggrandizing government departments and employees ensures their work expands to demand new revenue. The dominant voices in a media system that thinks publicly funded services are morally superior to private-sector activity drives the ratchet upward.

Now and then, with a Herculean effort, a truly determined government can push back and temporarily reverse or at least halt the movement. But the forces of expansion soon reassert themselves.

It is this iron law of fiscal expansion that helps explain the turmoil that has engulfed the new British government of

Liz Truss.

Two weeks ago,

Boris Johnson’s

successor launched a new fiscal plan. The main elements of it were tax cuts—a reduction in the basic rate of income tax, the cancellation of a payroll-tax increase and a planned corporate tax increase, and the elimination of a 45% income-tax rate, reducing the top bracket to 40%. The plan was controversial in two ways that have large resonance for the wider world: a financial one and a political one.

Start with the politics. Every bien-pensant intendant of our statist establishment denounced the decision. “I am sick and tired of trickle-down economics,” Joe Biden tweeted, in a subtle and undiplomatic dig at the domestic policy of our principal ally.

The International Monetary Fund, an institution whose job was once to provide assistance to countries with external account difficulties, but which is now a loyal foot soldier in the fight for a more equitable world, attacked the proposals for increasing inequality.

The financial press, which used to try to assess the economic effects of government decisions dispassionately, but is now a wholly owned mouthpiece of the left, chimed in.

The Financial Times, in an article accompanied by colorful graphs and ersatz statistical analysis, claimed that the British Conservative Party is now the most right-wing political party on economics in the developed world. A handy dot chart located the Tories as the precise ideological counterpoint to the Cuban Communist Party.

To hear these accusations of extremism, you would think the Truss government had abolished unemployment insurance, repealed child-labor laws or eliminated the national pension.

You probably wouldn’t have guessed that, after these measures, the size of the U.K. tax burden has gone all the way back to what it was in 2021. You wouldn’t have guessed that Ms. Truss’s party is committed to full taxpayer funding of universal healthcare in perpetuity. Or that at the same time as it was announcing its tax plans, it launched a package of spending to cap energy bills for consumers whose total cost dwarfs the revenue impact of the tax cuts.

But there it is—the ratchet effect. Try to shave a little off tax to improve incentives for work and investment and raise Britain’s abysmal productivity, and you are cast by the vast army of U.S. and international financial bureaucrats, socially conscious asset managers and media organizations as a heartless Hayekian tyrant, kicking away the crutches that keep Brits from being consigned to the poorhouse.

This is not to suggest that politics lay behind the financial market reaction to the proposals. The financial response that saw a selloff in the pound (since half-retraced) and in government debt (forcing a Bank of England intervention to avert systemic crisis) arose primarily from the poor timing of the package. The Truss team’s real error was to present a massive fiscal loosening—with no guidance on how it would be funded—at almost precisely the moment that the markets had been seized by bond vigilantes, suddenly on the lookout for the slightest hint of fiscal irresponsibility in an era of surging inflation.

This poor macroeconomic management hurt the rollout of the tax cut plan. But make no mistake: The larger threat to it comes from political resistance to the very idea of reducing the state. It is striking how many figures at her own party conference this week are trying to torpedo the idea. And on Monday the government bowed to the pressure, announcing it was dropping the planned cut in the top rate. Doubtless there will be more submissions to the ratchet.

The wider message for conservatives everywhere: Any effort to depart from the trajectory of expanding government will be met with fierce resistance. Flinch and watch as the ratchet moves higher.
