Capital is routinely withheld from the market for no reason other than the speculative expectation that a better price can be secured, and the owner’s right to withhold it—to wait, refuse prevailing terms, leave it idle, or abandon the market altogether—is ordinarily taken for granted.
As a matter of theoretical rigour, if capital can be withheld in its own self-interest, to the extent that financial means permit, why not embrace that same speculative instinct when it is extended to labour as a productive entity?
Labour need not itself possess the capital required to speculate. Financial capital could fund labour’s refusal of prevailing terms and take a contractual share of the economic gain thereby secured.
