“Constitutionalism”

It is widely acknowledged by Locke scholars that his economic views were essentially mercantilist. Keynes suggested that Locke stood with "one foot in the mercantilist world and one foot in the classical world." However that may be, chapter five of Locke's Second Treatise on Civil Government, "Of Property", is relentlessly, incorrigibly, two-footedly mercantilist. And nobody seems to have noticed (except possibly John R. Commons [correction: C.B. MacPherson stressed Locke's mercantilism in chapter 5]). 

Why would this even matter?

And it's crap. 

But there are bigger fish to fry: LABOUR. While socialists and even liberals may be inclined to circumscribe the sanctity of property, they are loath to gainsay the hallowed individualist framing of labour. Some folks even think it's downright revolutionary to insist on the worker's right to the whole product of labour. Labour, though,  is only conventionally something an individual performs. Labour is social. Labour power is best understood as a common-pool resource. 

The ideology of labour as an extension of the self is pervasive, persuasive and pernicious. From that perspective, solidarity is a voluntary act of magnanimity that can be "terminated at will" just like a redundant employee. As individuals, the relationship between workers is accidental; their relationships with the employer and with the state are what matters. 

The inescapable mercantilism of Locke's notion of natural law puts that individualist ideology in a different light. In his Essays on the Law of Nature (VIII), Locke was adamant that "the rightness of an action does not depend on its utility; on the contrary, its utility is a result of its rightness." "It is impossible," Locke wrote, "that the primary law of nature is such that its violation is unavoidable. Yet, if the private interest of each person is the basis of that law, the law will inevitably be broken..." 

Here is where the mercantilism comes in: "when any man snatches for himself as much as he can, he takes away from another man’s heap the amount he adds to his own, and it is impossible for anyone to grow rich except at the expense of someone else." To avoid any mistake, Locke reiterates his objection to positing "every man's self interest the basis of natural law":

"For in such a case each person is required to procure for himself and to retain in his possession the greatest possible number of useful things; and when this happens it is inevitable that the smallest possible number is left to some other person, because surely no gain falls to you which does not involve somebody else's loss."

Now there are those who will object that Locke modified his views between the earlier Essays on the Law of Nature and his later Second Treatise on Civil Government. Not so. In the latter, and especially in the chapter "Of Property," Money plays a pivotal role in repealing what has become known as the spoilage limitation:

"He that gathered a hundred bushels of acorns or apples, had thereby a property in them... He was only to look, that he used them before they spoiled, else he took more than his share, and robbed others. And indeed it was a foolish thing, as well as dishonest, to hoard up more than he could make use of." 

How does Money nullify that limitation? The person who gathers more perishable goods than he can use can exchange it for durable Gold or Silver. Problem solved.

Locke was a staunch metallist who insisted on the intrinsic value of Money as represented by its weight and fineness. This is not some incidental biographical trivia. Locke's well documented views on Money were decisive in the monetary reform and re-minting of British coinage in the 1690s.

According to Locke, it was not the absolute quantity of Gold and Silver a nation held that determined its wealth but the proportion of Gold and Silver it held relative to the holdings of the rest of the world:

"Riches do not consist in having more Gold and Silver, but in having more in proportion, than the rest of the World, or than our Neighbours, whereby we are enabled to procure to our selves a greater Plenty of the Conveniencies of Life than comes within the reach of Neighbouring kingdoms and States, who, sharing the Gold and Silver of the World in a less proportion, want the means of Plenty and Power, and so are Poorer." 

Postscript 

Some readers may have wondered at the parenthetical reference to John R. Commons back in the second paragraph. Commons didn't specifically address the passages I cited from the Essays on the Law of Nature. In fact, it wasn't published until 20 years later. Nor did he discuss Locke's influential writings on Money. But he did make a point in a reply to a critic that is germane to my argument here. 

The context of Commons's observations is crucial to the significance of his remark, so I will reproduce a substantial excerpt here:

My point of view is indeed personal, as was said by Professor Homan of all institutional economists. It is simply my own experience in collective action from which I drew a theory of the part played by collective action on individual action. It may or may not fit other people's ideas of institutionalism. It started, indeed, with my trade-union membership and my later participation in labor arbitration; then turned to drafting a public utility law designed to ascertain and maintain reasonable values and reasonable practices; then to drafting and participating in administration of an industrial commission law with the similar purpose of reasonable practices applied to employers and employees; then to representing the western states before the Federal Trade Commission on the Pittsburgh Plus case of discrimination; then to aiding the House Committee on Congressman Strong's bill for stabilization of prices; meanwhile administering and developing a plan for unemployment insurance finally enacted into law.

I do not see how anyone going through these 45 years of participation could fail to arrive at two inferences, conflict of interest and collective action. Even the state itself turned out to be merely collective action of those in possession of sovereignty.

Meanwhile I was necessarily studying hundreds of decisions, mainly of the United States Supreme Court, endeavoring to discover on what principles they decided disputes of conflicting interests under the clauses of the Constitution relating to due process, to taking property and liberty, and to equal treatment. I found that none of the economists had taken this point of view, and none of them except Professor Ely, had made any contributions that would make it possible to fit legal institutions into economics or into this constitutional scheme of American judicial sovereignty.

Going back over the economists from John Locke to the orthodox school of the present day, I found they always had a conflicting meaning of wealth, namely a material thing and the ownership of that thing. But ownership, at least in its modern meaning of intangible property, means power to restrict production on account of abundance while the material things arise from power to increase the abundance of things by production, even overproduction.
