A great estate is a balance sheet that other people must live beside. It may contain useful businesses, houses, loans and savings, each with a price and each with a history. Together they give the owner an enduring capacity to choose: to spend or withhold, to continue a project or close it, to accept terms or wait for better ones. The volume began by distinguishing a stock from a flow, then asked how the stock became a claim. It closes with the position sustained by that claim. What should a commonwealth of equals make of a fortune that passes from one holder to another while the freedom it supplies remains far beyond what most people can earn?
The case for ownership begins with goods a decent society has reason to protect. People need a reliable claim to the fruits of useful work, room to undertake uncertain projects, and a reserve against dependence. They may reasonably want to provide for a child or preserve something built with others. Mill's defense of property gave productive effort and saving a central place while recognizing that the present possessor might have received the result from somebody else. That defense deserves its full force. An institution that made every successful undertaking immediately available for arbitrary seizure would damage security as well as enterprise. But a reason for reliable possession leaves further questions about the forms, duration and concentration of the rights it protects.
The maker's contribution and the successor's entitlement are different parts of that further inquiry. A business may have begun with an invention that served customers well, expanded under competent management and later passed to an heir who appoints other people to run it. Its useful work can continue throughout. The origin can justify reward without supplying an endless biography of merit for every subsequent recipient. Conversely, an heir can make contributions of their own, and those contributions deserve to be judged on their merits. Keeping the histories separate clarifies the claims: a reward needs an identified service, while succession needs an account of why that service gives someone else the proposed position.
A fortune supplies independence even when it is yielding no income. Imagine two people whose regular earnings have stopped, each needing ten a month to maintain a stipulated basic standard. One has a liquid reserve of a hundred and the other twenty, with no interest, debt, other income or outside help. The first can wait ten months; the second two. They have the same current earnings and very different room to refuse a bad offer. The reserve makes an option feasible that temperament alone cannot provide. If both reserves are inaccessible during the interval, that particular capacity disappears, which is why the valuation of wealth and its immediate availability must be kept distinct.
The distribution of that independence matters even if no one uses wealth to command anyone else. A person who can finance retraining, endure a search or leave a harmful arrangement has possibilities that an equally able person without a reserve may lack. Public provision, insurance and enforceable rights can supply parts of the same protection, so the private balance sheet is not a complete inventory of freedom. Yet the observation points toward a clear social purpose: widen the effective ability to withstand a setback and choose a course. Making everyone equally exposed would satisfy neither that purpose nor the argument of this volume. The question is how security can become ordinary rather than remain a distinction of birth.
Some holdings confer authority over resources on which other people depend. The owner of a workshop can have powers about its use that a holder of a small, passive claim lacks; the effect depends on the rights attached to the holding and the alternatives available to those affected. A valuation does not reveal that arrangement by itself. Consider the same productive assets worth a hundred under two stipulated constitutions: one gives a sole owner the decisive vote, and another gives four equal owners one vote each. The total value is held fixed, while authority is distributed differently. Real changes of governance may alter production and value, but the comparison identifies what an aggregate number leaves out. The estate is an arrangement of powers as well as a sum.
Wealth can also purchase ways of reaching the common discussion without thereby proving that every wealthy person controls it. A person able to finance a publication, support a campaign of persuasion or maintain an organization has means that another may lack. The question for political equality concerns the channels through which those means become public authority: who can be heard, who decides, what is disclosed and which decisions remain accountable to everyone affected. These are institutional questions. An inference that every large fortune buys obedience would evade the need to answer them, just as a declaration that all private spending is merely personal would evade the possibility that its effects extend beyond the spender.
Mill treated the attempt to govern through property after death as a particular danger. His objection reached beyond an estate tied to a family line. A benefactor who endowed a school and prescribed its doctrines forever could also bind the living to a judgment made by the dead. The gift might be generous and the original purpose valuable, while the claim to perpetual direction outran what either justified. He therefore argued for later revision by a suitable authority. The point carries a wider lesson: a public benefit and an unanswerable power can be bundled in the same disposition. Recognizing the benefit does not require treating every attached instruction as entitled to endure forever.
Checking inherited position can accordingly take more than one form. Mill's proposal to limit what an individual might receive aimed to multiply people with comfortable independence, while allowing a qualification for keeping a productive enterprise under suitable control. Other arrangements can distinguish income rights from management, alter the distribution of ownership, or provide common services that reduce dependence on a private reserve. Each must be judged in its own terms. A change that broadens the receipt of income may leave control concentrated; a change in control may leave income unequal; a public service may widen effective opportunity without appearing in private wealth. The objective should determine the instrument and the evidence by which its performance is assessed.
A simple redistribution account shows both the reach and the limit of arithmetic. Suppose ten people together own a hundred, one holding ninety and the other nine sharing ten equally. Transfer eighteen from the largest holding in equal amounts to the other nine, ignoring costs and behavioral change. The first now has seventy-two and each of the others a little over three. Total wealth remains a hundred; the largest share falls from ninety to seventy-two percent, and the smaller holdings become more useful reserves. The account establishes a distributional change. It does not establish that the transfer was lawful, that its design preserved useful incentives, or that the resulting distribution meets a chosen standard of justice. Those require reasons beyond the sum.
The limits of an account are a reason to demand better reasons from ownership, not a reason to give it immunity from judgment. The possibility that a return encourages useful effort must be connected to the effort it is supposed to encourage. The reliance created by an established rule deserves examination without making the rule incapable of revision. A parent's freedom to give matters without exhausting a child's relation to everyone else. And the security that property supplies is a reason to care about its distribution as well as its protection. The question is no longer whether the estate can be called earned in a single word, but which of its claims can survive being stated in full.
The title carries a claim; the commonwealth must decide what that claim may command.
The reservoir is useful because it stores possibilities through time. The claim becomes politically troubling when those possibilities harden into a rank that others must accommodate and that its holder need never justify. A commonwealth can honor creation, protect a reserve and permit affection to cross a generation while still asking how much enduring power should accompany the transfer. The estate's history deserves to be known; its present authority deserves to be examined. That is the distinction the next volume carries into The Power, where command over an exchange becomes the subject directly. The argument remains open.
