Recognizing that income tax brackets as high as 80 percent typically raise little revenue (because they induce strong tax avoidance efforts), Piketty comments that “the primary goal [of imposing such rates] is obviously not to raise additional revenue.” If so, it follows that the goal is not to transfer resources to the poorest. He explains: “It is rather to put an end to such incomes and large estates, which lawmakers have for one reason or another come to regard as socially unacceptable and economically unproductive” (p. 505).

² The Supplemental Nutrition Assistance Program (“food stamps”) disbursed $70 billion to 47 million recipients; Supplemental Security Income, $54 billion to about 8 million recipients (calendar year 2014); Temporary Assistance to Needy Families, $32 billion; federal housing assistance programs, $50 billion; federal child care assistance, $9 billion (FY 2013, the most recent figure available); means-tested employment training programs (not already counted as part of TANF or SNAP), $15 billion. An older study of US transfer programs is provided by Robert Moffitt, ed., Means-Tested Transfer Programs in the United States (Chicago: University of Chicago Press for the National Bureau of Economic Research, 2003). The dollar figures come from the appropriate federal agency websites, except job training program expenditures from Burt S.

²¹ I have elsewhere noted that the Pareto efficiency criterion cannot even judge slavery to be inefficient relative to free labor, in the sense that from the standpoint of a slave-owning property rights system unilaterally freeing slaves is taking people’s property, and the Pareto criterion by itself does not favor one set of property rights over another (White, Lawrence H., “Can Economics Rank Slavery Against Free Labor in Terms of Efficiency?” Politics, Philosophy, and Economics 7, no. 3 [2008]: 327–40)CrossRefGoogle Scholar.

³⁰ Here “leisure” can stand for any non-monetary benefit that the individual trades off against higher income, such as greater intellectual stimulation or autonomy or lower stress on the job, or living in a more pleasant location. When different people choose different combinations of income and happiness from non-monetary sources, observed income is an unreliable proxy for happiness. (I am indebted to Todd Zywicki for discussion here.)

³¹ Strictly speaking, the theoretical result follows for a tax on income from the marginal hour of work, while holding the individual’s disposable income (or total tax burden) constant. For example, it holds when the marginal income tax rate is increased but other taxes are reduced to keep the average tax rate and thus disposable income constant. A higher marginal income tax rate not offset by tax reductions elsewhere reduces the individual’s total disposable income, and it is possible that the taxed individual would then choose more work effort to return toward his original disposable income level. In other words, at a lower disposable income level the marginal preference for income over leisure is stronger. This “income effect” could in principle dominate the “substitution effect.” But econometric evidence for the United States indicates that the substitution effect dominates the income effect in practice. That is, a higher tax rate reduces hours worked (especially for women, who more often work part-time) despite lowering disposable income.

³³ Again, strictly speaking, the result follows while holding the saver’s or investor’s total lifetime tax burden constant to isolate the substitution effect.

⁴⁶ If we magically had a demand revelation mechanism, we might still need collectively arranged rather than ordinary user-pays provision because of a strategic problem: I won’t pay my share unless I know that others will also pay theirs. But collective provision could proceed voluntarily, on the basis of actual consent, via a binding agreement to contribute that does not go into effect until all sign it (what Schmidtz, David, The Limits of Government [Boulder, CO: Westview Press, 1991Google Scholar] calls an assurance contract). We would not be asked to regard mere suppositions about willingness to pay as a justification for what, in the absence of actual consent to pay, is coercive taxation.

⁴⁹ Thus Leggett, William, “True Functions of Government” [1834], in Leggett, Democratick Editorials, ed. White, Lawrence H.

The functions of Government, when confined to their proper sphere of action, are therefore restricted to the making of general laws, uniform and universal in their operation, for these purposes, and for no other. . . . . Whenever a Government assumes the power of discriminating between the different classes of the community, it becomes, in effect, the arbiter of their prosperity, and exercises a power not contemplated by any intelligent people in delegating their sovereignty to their rulers. . . . No nation, knowingly and voluntarily, with its eyes open, ever delegated to its Government this enormous power, which places at its disposal the property, the industry, and the fruits of the industry, of the whole people.”
