What Markets Leave Behind

The debate over public versus private provision is often clouded by abstractions, such as “efficiency,” “innovation” and “choice.” Strip those away, and what remains is a simpler question: Who gets served and who gets left out.

Public systems, for all their flaws, are built to include. Private systems, by design, are built to exclude those who cannot pay.

Private markets do not fail when they leave people out. They are doing exactly what they are supposed to do: allocate goods and services to those with the means to purchase them. The language of “failure” is misleading. There is no failure from the vantage point of the private interests’ CFOs when an uninsured person is denied care, or when a family is priced out of housing. The system is working as designed. The outcome is simply inconvenient for those without money.

Public systems in contrast operate under a different mandate. They are tasked with ensuring that certain basic needs are met regardless of income. They do this imperfectly, yes, often inefficiently, and sometimes clumsily. But they do it. And that difference is not marginal. It is decisive.

Consider healthcare. Left to its own devices, the private insurance industry segments risk with precision. The healthy are rewarded. The sick are penalized. Coverage becomes narrower as costs rise, and those who need care most often face the greatest barriers. Regulation can blunt these edges, but it cannot eliminate the underlying incentive: Avoid the costly, serve the profitable.

Public systems, on the other hand, spread risk across the entire population. They are not elegant or fast. But they do something private systems do not: They guarantee a floor. You may wait longer than you wished to wait. You may navigate an annoying bureaucracy. But you are not simply discarded because your condition is expensive.

Housing tells the same story. Developers build where profits are highest, not where needs are greatest. The result is predictable: Luxury units rise while affordable housing lags behind demand. The market signals are clear, and they are followed. Those without sufficient income are not misserved, they are not served at all.

Public housing exists because of that gap. It is rarely celebrated, often criticized and frequently underfunded. Yet where it functions, it does something the market does not reliably do: It provides stability for those who would otherwise have none.

Finance offers no exception. Banks extend credit where returns are secure. Communities with lower incomes, higher perceived risks or less historical capital are routinely bypassed. This is called efficiency. It is also exclusion.

Public lending programs, credit unions and government guarantees step in not because markets are misunderstood, but because they are understood too well. Left alone, they will not serve everyone.

The pattern repeats across sectors. It is not about which system is more efficient in a narrow technical sense. It is about what each system is built to accomplish.

Private systems operate under a whole different regime: They are tuned to price signals. Public systems, in sharp contrast, are tasked with meeting needs.

When those two align, there is little conflict. But in essential services, healthcare, housing, access to justice and basic utilities, they do not align. And when they diverge, the consequences are not abstract. They are measured in shortened lives, unstable homes and diminished chances.

Defenders of private markets often point to competition as a remedy. Increase it, and the system will correct itself. First, one must note that such defenders of private markets are usually the most vociferous voices against any antitrust interventions by the government to step in to prevent the emergence of monopolies. But even granting them the point, the fact is that competition does not change the operating fundamental rule of for gain and for profit enterprises: Those who cannot pay are not customers. They are invisible.

To be sure, critics are right to point out the shortcomings of public institutions. Bureaucracy can be slow. Management can be poor. Accountability can falter. Corruption does exist here and there. These are real problems, and they demand correction.

But private systems have their own predictable shortcomings. Slow bureaucracy (often worse than that of public systems), bad management (almost always worse than that of public systems), lack of accountability (always infinitely worse than that found in public systems) and rank corruption (which, unlike public systems, is done openly and without apology, and almost festively, as if to demonstrate that the rule law is for suckers and the spoils of financial success for winners).

The central point though is this: A system that guarantees imperfect inclusion will, in matters of public welfare, outperform a system that delivers supposed and often dubious “efficient” exclusion. As the examples above illustrate, this is a basic demonstrable fact that one should always keep in mind when confronted with the proposition that the welfare of the public should be entrusted to private, unaccountable, always greedy interests.

The question, then, is not which system is cleaner on paper or more elegant in theory. It is which system is willing to take responsibility for everyone. On that measure, the answer has been obvious for a long time.
