Plenitude is the positive counterpart to Schor's diagnostic work. Where The Overworked American and The Overspent American documented what was wrong with the American economic architecture, True Wealth (also published as Plenitude) articulated an alternative. Plenitude is an economics of enough — not austerity, not voluntary poverty, but a deliberate design choice to cap output at sufficiency and direct surplus capacity toward time, relationship, self-provisioning, and sustainability. The four core principles are reduced work hours, diversified economic activity, investment in ecological sustainability, and cultivation of production outside the formal market. The AI moment is the most powerful test of the framework that has ever presented itself, because AI produces the productivity surplus required to fund plenitude without reducing material standard.
The framework emerged from Schor's recognition that diagnosing the overwork and overconsumption problems was insufficient without articulating a viable alternative. The alternatives available in the early 2000s — mainstream policy reforms, voluntary simplicity movements, degrowth economics — each captured part of what was needed but none assembled the full institutional architecture required to shift the American economy away from the work-spend cycle.
Plenitude's four principles operate together, not separately. Reduced work hours create time for the other three. Diversified economic activity — combining formal employment with self-provisioning, cooperative production, and non-market exchange — reduces dependence on any single income source. Investment in ecological sustainability both responds to environmental constraints and reduces the consumption-treadmill pressure that drives overwork. Cultivation of non-market production — gardening, repair, caregiving, creative work — provides sources of meaning and material benefit that do not require income, breaking the income-hours lock-in.
The AI connection is direct. Plenitude requires productivity gains to be captured as time and sustainability rather than output; AI provides the largest productivity surplus in history; the question is whether the institutional architecture will be built to redirect the surplus. Schor's argument in On AI is that the ascending friction Segal identifies in The Orange Pill — the migration of work from implementation to judgment — reinforces the plenitude framework, because judgment, care, and relationship work operate on temporal rhythms that are natively compatible with plenitude's reduced-hour architecture.
Critics of plenitude have objected that it requires cultural transformation at scales that institutional design alone cannot achieve. Schor's response, consistent across her career, is that cultural change and institutional change are mutually reinforcing — that the eight-hour day required both institutional victory (legislation, union recognition) and cultural shift (the normalization of leisure as morally acceptable), and that neither happens without the other.
Published as Plenitude: The New Economics of True Wealth (Penguin Press, 2010), and reissued in paperback as True Wealth (2011), the framework extended Schor's diagnostic work into constructive policy design.
The book's framework drew on Schor's work with the MacArthur Foundation Research Network on the Connected Learning Research Network, her fieldwork on alternative economic communities, and her engagement with European social-democratic policy traditions.
Sufficiency over maximization. The goal is enough output to sustain wellbeing, not maximum output to sustain growth.
Four interlocking principles. Reduced hours, diversified activity, sustainability, and self-provisioning operate together, each enabling the others.
Time as the scarce resource. In a plenitude economy, time is the binding constraint and the most valuable good — the resource that productivity gains should purchase.
Cultural and institutional change. The reform requires simultaneous change in compensation structures, regulatory frameworks, and cultural norms about what a good life requires.
AI as enabling condition. The productivity surplus AI delivers is large enough to fund plenitude's reduced hours without reducing material standard — the arithmetic works if the institutions are built.
The central debate concerns whether plenitude is scalable. Advocates argue that the four-day workweek pilots demonstrate scalability; critics argue that pilot conditions do not generalize, that the self-provisioning and diversified-activity components require cultural and skill shifts that policy cannot mandate, and that the global competitive dynamics of capitalism punish any economy that unilaterally adopts plenitude principles. The AI moment sharpens this debate because AI's productivity surplus is large enough to overcome the competitive penalty if institutions are designed to capture it — but only if they are.
