(4) The Benefit Principle

The benefit principle differs radically from the two preceding criteria of taxation. For the sacrifice and ability-to-pay principles depart completely from the principles of action and the accepted criteria of justice on the market. On the market people act freely in those ways which they believe will confer net benefits upon them. The result of these actions is the monetary exchange system, with its inexorable tendency toward uniform pricing and the allocation of productive factors to satisfy the most urgent demands of all the consumers. Yet the criteria used in judging taxation differ completely from those which apply to all other actions on the market. Suddenly free choice and uniform pricing are forgotten, and the discussion is all in terms of sacrifice, burden, etc. If taxation is only a burden, it is no wonder that coercion must be exercised to maintain it. The benefit principle, on the other hand, is an attempt to establish taxation on a similar basis as market pricing; that is, the tax is to be levied in accordance with the benefit received by the individual. It is an attempt to achieve the goal of a neutral tax, one that would leave the economic system approximately as it is on the free market. It is an attempt to achieve praxeological soundness by establishing a criterion of payment on the basis of benefit rather than sacrifice.

The great gulf between the benefit and other principles was originally unrecognized, because of Adam Smith's confusion between ability to pay and benefit. In the quotation cited above, Smith inferred that everyone benefits from the State in proportion to his income and that this income establishes his ability to pay. Therefore, a tax on his ability to pay will simply be a quid pro quo in exchange for benefits conferred by the State. Some writers have contended that people benefit from government in proportion to their income; others, that they benefit in increased proportion to their income, thus justifying a progressive income tax. Yet this entire application of the benefit theory is nonsensical. How do the rich reap a greater benefit proportionately, or even more than proportionately, from government than the poor? They could do so only if the government were responsible for these riches by a grant of special privilege, such as a subsidy, a monopoly grant, etc. Otherwise, how do the rich benefit? From “welfare” and other redistributive expenditures, which take from the rich and give to the bureaucrats and the poor? Certainly not. From police protection? But it is precisely the rich who could more afford to pay for their own protection and who therefore derive less benefit from it than the poor. The benefit theory holds that the rich benefit more from protection because their property is more valuable; but the cost of protection may have little relation to the value of the property. Since it costs less to police a bank vault containing $100 million than to guard 100 acres of land worth $10 per acre, the poor landowner receives a far greater benefit from the State's protection than the rich owner of personalty. Neither would it be relevant to say that A earns more money than B because A receives a greater benefit from “society” and should therefore pay more in taxes. In the first place, everyone participates in society. The fact that A earns more than B means precisely that A's services are individually worth more to his fellows. Therefore, since A and B benefit similarly from society's existence, the reverse argument is far more accurate: that the differential between them is due to A's individual superiority in productivity, and not at all to “society.” Secondly, society is not at all the State, and the State's possible claim must be independently validated.

Hence, neither proportionate nor progressive income taxation can be sustained on benefit principles. In fact, the reverse is true. If everyone were to pay in accordance with benefit received, it is clear that (a) the recipients of “welfare” benefits would bear the full costs of these benefits: the poor would have to pay for their own doles (including, of course, the extra cost of paying the bureaucracy for making the transfers); (b) the buyers of any government service would be the only payers, so that government services could not be financed out of a general tax fund; and (c) for police protection, a rich man would pay less than a poor man, and less in absolute amounts. Furthermore, landowners would pay more than owners of intangible property, and the weak and infirm, who clearly benefit more from police protection than the strong, would have to pay higher taxes than the latter.

It becomes immediately clear why the benefit principle has been practically abandoned in recent years. For it is evident that if (a) welfare recipients and (b) receivers of other special privilege, such as monopoly grants, were to pay according to the benefit received, there would not be much point in either form of government expenditure. And if each were to pay an amount equal to the benefit he received rather than simply proportionately (and he would have to do so because there would be nowhere else for the State to turn for funds), then the recipient of the subsidy would not only earn nothing, but would have to pay the bureaucracy for the cost of handling and transfer. The establishment of the benefit principle would therefore result in a laissez-faire system, with government strictly limited to supplying defense service. And the taxation for this defense service would be levied more on the poor and the infirm than on the strong and the rich.

At first sight, the believer in the free market, the seeker after a neutral tax, is inclined to rejoice. It would seem that the benefit principle is the answer to his search. And this principle is indeed closer to market principles than the previous alleged canons. Yet, if we pursue the analysis more closely, it will be evident that the benefit principle is still far from market neutrality. On the market, people do not pay in accordance with individual benefit received; they pay a uniform price, one that just induces the marginal buyer to participate in the exchange. The more eager do not pay a higher price than the less eager; the chess addict and the indifferent player pay the same price for the same chess set, and the opera enthusiast and the novice pay the same price for the same ticket. The poor and the weak would be most eager for protection, but, in contrast to the benefit principle, they would not pay more on the market.

There are even graver defects in the benefit principle. For market exchanges (a) demonstrate benefit and (b) only establish the fact of benefit without measuring it. The only reason we know that A and B benefit from an exchange is that they voluntarily make the exchange. In this way, the market demonstrates benefit. But where taxes are levied, the payment is compulsory, and therefore benefit can never be demonstrated. As a matter of fact, the existence of coercion gives rise to the opposite presumption and implies that the tax is not a benefit, but a burden. If it really were a benefit, coercion would not be necessary.

Secondly, the benefit from exchange can never be measured or compared interpersonally. The “consumers’ surplus” derived from exchange is purely subjective, nonmeasurable, and non-comparable scientifically. Therefore, we never know what these benefits are, and hence there can be no way of allocating the taxes in accordance with them.

Thirdly, on the market everyone enjoys a net benefit from an exchange. A person's benefit is not equal to his cost, but greater. Therefore, taxing away his alleged benefit would completely violate market principles.

Finally, if each person were taxed according to the benefit he receives from government, it is obvious that, since the bureaucracy receive all their income from this source, they would, like other recipients of subsidy and privilege, be obliged to return their whole salary to the government. The bureaucracy would have to serve without pay.

We have seen that the benefit principle would dispense with all subsidy expenditures of whatever type. Government services would have to be sold directly to buyers; but in that case, there would be no room for government ownership, for the characteristic of a government enterprise is that it is launched from tax funds. Police and judicial services are often declared by the proponents of the benefit principle to be inherently general and unspecialized, so that they would need to be purchased out of the common tax fund rather than by individual users. However, as we have seen, this assumption is incorrect; these services can be sold on the market like any others. Thus, even in the absence of all other deficiencies of the benefit principle, it would still establish no warrant for taxation at all, for all services could be sold on the market directly to beneficiaries.

It is evident that while the benefit principle attempts to meet the market criterion of limiting payment solely to beneficiaries, it must be adjudged a failure; it cannot serve as a criterion for a neutral tax or any other type of taxation.
