When voters outpace the ideologues

The New York Post reports that Missouri voters have overwhelmingly rejected a ballot measure to abolish the state income tax — a result that, on the surface, looks like mere fiscal timidity but is, on closer inspection, something rather more instructive.

The case for abolition rests on a household analogy that I have spent a professional lifetime disputing. The argument runs: taxes are a burden; burdens should be lightened; therefore abolish the tax and let commerce flourish. It is the argument of the individual saver transposed, without examination, onto the public accounts. What it omits is the question of what replaces the revenue — and the New York Post's lead is admirably direct on this point: Missouri voters apparently feared an increase in other forms of taxation to make up for the loss. That is not irrationality. That is incipient macroeconomic literacy.

Nine states have, by the same account, phased out individual income taxes. I make no claim about the detailed fiscal engineering of any of them — the mechanics of modern state budgets are beyond what I can speak to with authority. But I can say this: the question is never whether a government collects revenue, but how it does so, and whether the distribution of that burden is consistent with the aggregate demand the economy requires. A shift from a progressive income tax to sales taxes or property levies tends to concentrate the fiscal weight on those with the highest marginal propensity to consume — which is to say, on precisely the households whose spending sustains the circular flow of income. That is a structural drag, not a stimulus.

The deeper lesson is about animal spirits in reverse. Investment and consumption are animated by confidence — confidence that public services will be maintained, that the infrastructure of commerce will hold, that the social contract will not be quietly dissolved by a ballot initiative drafted in the language of liberty. When voters sense that a sweeping fiscal change may simply relocate their tax burden rather than eliminate it, they are, whether they know it or not, discounting the promised stimulus against the probable cost. That is rational. Sophisticated, even.

I would be careful not to read this result as a mandate for high taxation as such. The proper lesson is narrower and more durable: fiscal architecture matters, and voters can tell — imperfectly, collectively, but often correctly — when a proposed change is more theatrical than transformative. The job of policymakers is to match revenue design to the economy's actual structure, not to chase the applause of those who believe that any tax cut is self-evidently a public good. Missouri's electorate, it appears, was not buying it. Neither, on the evidence, should we.
