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
