New York Mayor Mamdani’s proposed 30 percent discount on groceries is a textbook case of the seen. It is immediate, easy to picture, and politically appealing—shoppers checking out and paying less. But Hazlitt’s lesson demands a harder question: where did the other 30 percent go? Costs do not vanish because the government owns the store. They simply become less visible, paid by someone, somewhere, who isn’t standing at the register.

The lower price at the register is the visible part of the policy—what every shopper sees, every time, at checkout. But Hazlitt’s method requires looking past the immediate effect to the less obvious one. If a grocery store sells food below its true cost, someone else must make up the difference. The question is never whether consumers receive a discount. It’s whether that discount represents real savings or simply moves part of the bill somewhere else.

In a private market, a discount usually reflects lower costs, greater efficiency, or a business voluntarily sacrificing some profit to win customers. Whoever offers the discount also bears its cost. A government-run grocery store breaks that link. If it consistently sells below the cost of providing groceries, the shortfall doesn’t disappear—it gets financed through public funds. Part of the grocery bill simply moves from the checkout counter to the tax bill.

The unseen cost doesn’t stop at the subsidy itself. Every dollar spent keeping prices artificially low is a dollar that can’t be spent on anything else. Those same funds could have stayed with taxpayers to spend or invest as they saw fit, or been directed to other public services entirely. Government cannot manufacture new purchasing power by changing who writes the check. It can only redirect resources from one use to another—and every redirection has a cost that goes unseen by the person enjoying the discount.

The subsidy doesn’t just move money around—it changes the competitive landscape those dollars flow into. Independent grocers and family-owned markets cover their costs through sales alone. They pay rent, utilities, payroll, and inventory out of what customers actually spend with them, with no public backstop if the math doesn’t work. A government-run store selling similar groceries at subsidized prices puts those businesses at a disadvantage—not because they’re less efficient, but because they’re competing against a rival whose losses are covered by taxpayers rather than corrected by the market.

This is precisely the kind of effect Hazlitt warned readers to look for: the one that doesn’t show up in the first day’s headlines. Competition is what forces every grocery store to keep prices low, shelves stocked, and service sharp—because shoppers always have somewhere else to go if a store falls short. Subsidize one competitor, and that discipline weakens for everyone else. Some independent grocers may respond by cutting already thin margins further. Others may not be able to compete at all.

Hazlitt’s most famous illustration was the broken window: a vandal smashes a shopkeeper’s window, and onlookers console themselves that at least the glazier gets new business. What they don’t see is what the shopkeeper would have bought instead—a suit, tools, inventory—and the jobs that spending would have supported. The visible job created by the break obscures the invisible ones destroyed by it.

The same logic applies here. A new government-run grocery store creates visible jobs—cashiers, stockers, managers, a ribbon-cutting with local officials on hand to take credit. Those jobs are easy to point to and easy to photograph. What’s harder to see is the independent grocer down the street who loses enough customers to cut a shift, delay a hire, or close entirely. Those jobs don’t disappear with a headline. They simply never appear, or they quietly end, and no one holds a ceremony for them.

This is not an argument that government stores create zero jobs. It’s an argument that counting only the jobs it visibly creates, while ignoring the ones it invisibly displaces, is exactly the kind of one-sided accounting Hazlitt spent his career warning against. The full ledger includes both sides—the seen hire and the unseen layoff—and only one of them tends to make the news.

None of this diminishes the real strain rising food prices put on family budgets. Groceries have become one of the fastest-growing line items in household spending, and the frustration behind that is legitimate. The question was never whether food should be more affordable, it’s how. Markets lower prices by raising productivity, sharpening competition, and cutting the real cost of production. Subsidies do none of that; they don’t shrink the cost of producing food—they only decide who pays it, and how visibly.

A 30 percent discount makes for an easy headline, because the benefit is immediate and the beneficiary is standing right there at the register. The costs are quieter. They show up in higher taxes, in a grocer down the street who lays off a cashier, in the public services that don’t get funded because the money went to keeping shelves subsidized instead. Hazlitt’s one lesson was never that government spending has no effects—it’s that good economics means tracing all of them, not just the ones that make it into the ribbon-cutting photo.
