An arrangement can increase output while reducing the shifts its participants are able to refuse, the paths to which they are able to turn, and the time in which they are able to rest without interruption. These two changes do not contradict each other. Income growth remains income growth; it cannot be said not to have occurred merely because harm accompanies it, and by the same token income growth cannot answer for the harm. What this book adds is a second question: who obtains the growth, and what conditions of life are left to whom?

The three ledgers can now be closed again. The ledger of returns shows that the Linchuan program gained course completion rates, data, and organizational expansion, and that Ning acquired skills and a portion of the opportunities; the ledger of depletion shows that waiting, equipment, care, and recovery were not settled along with the income; the ledger of the future shows how credentials, debt, reputation, and data alter the road after exit. Growth in the first ledger alone does not prove harvesting; a harvesting relation holds only when the three ledgers remain separated over time and the same side has the power to define returns, displace depletion, and raise the future price of exit.

Invocation, displacement, locking, self-certification, and replacement are not five isolated injustices either. Invocation produces returns; displacement hides costs; locking extends invocation; self-certification interprets continued participation as free consent; and replacement enables the system to preserve an appearance of success after individuals have been exhausted. Only when the chain is connected again does the warning that "a person's possibility becomes a resource" acquire a testable object; and only when the chain is taken apart and checked link by link can we avoid mistaking every instance of labor, borrowing, or dedication for harvesting.

Ning, in the Linchuan skills program, is a fictional figure. She is willing to learn, and willing to forgo some immediate options for the sake of a long-term goal. This book has no reason to cancel these commitments on her behalf. The problem lies elsewhere: the conditions of the courses, credentials, and opportunities keep changing, the newly added costs fall on her, and she holds no corresponding position from which to evaluate and revise. The thought experiment makes this asymmetry easy to see, but it does not prove that training, debt, or platforms in reality necessarily operate this way. Judgment about reality requires contracts, time records, the allocation of costs, and the actual choices of the persons involved; it cannot be settled merely because a story resembles the case.

The Difference Between Dedication and Being Locked In

Future options are not the more the better. Learning a skill, sustaining a relationship, and caring for a person may all require long-term investment and the deliberate closing of some doors. If every commitment were treated as a loss of possibility, autonomy would shrink into the capacity to withdraw at any moment, and many lives worth living would become unintelligible.

Chapter 20's discussion of affordable exit does not establish a right that stands outside commitments and remains free of charge forever; it demands that costs and responsibilities be capable of justification. Exit cannot simply transfer existing obligations onto others; neither can continuation rest on penalties that keep increasing and cannot be foreseen. The difference is to be judged by what was known at entry, what changed afterward, who has the power to revise, and whether one can still live after exiting. A subject may choose dedication, but should not be able to sustain a commitment only by denying the depletion that has already occurred.

The ledger of recovery costs also has boundaries. It brings hidden labor into decisions, yet it cannot reconvert the whole of a person's time into a resource deliverable as output. Care, rest, and idleness do not possess only the value of "helping the next round of work." A more considerate management that required everyone to keep proving that they recover more efficiently could still acquire a new evaluation power over life. That certain time need not deliver results is a limit on this ledger itself.

The future space of choice is therefore a normative measure for evaluating growth, not a definition of whether growth is real, and not a physical quantity that can be synthesized into a total score. The "available margin" offers a direction of inquiry; it offers no formula by which the gains and losses of different persons can be set off against one another. Evaluation must keep the materials of output, distribution, recovery, and exit separate, and allow them to point toward inconsistent conclusions.

After the book is closed, what remain to be made are still concrete decisions. Ning's story cannot decide for anyone whether to borrow, to change jobs, or to return to study. What can be taken away is a method for checking a commitment: once the commitment has been honored, does the person still have the conditions to understand the situation, to change the decision, or to continue along the original path if willing?
