From Labour to Body: Participation Collapse Across Economic and Biological Systems

This paper advances a structural account of participation collapse across economic, biological, and psychological systems. Building on the Engagement Credit Economy (ECE) framework, it argues that the erosion of labour legitimacy in post-labour economies has a direct analogue in population-level health decline. In both domains, optimisation removes functional necessity without replacing participatory demand, producing fragility rather than freedom. Economically, automation and efficiency decouple income and legitimacy from contribution, generating surplus populations that are materially sustained but structurally unneeded. Biologically and psychologically, environments optimised for safety, convenience, and risk minimisation remove the need for embodied participation, leading to underdevelopment of physical capability, diminished self-efficacy, rising anxiety, chronic illness, and escalating healthcare costs. These outcomes are framed not as individual failure or lifestyle deficit, but as predictable system-level adaptations to low-demand environments. The paper reframes health as participation infrastructure: the capacity to engage meaningfully in social, economic, and civic life. It distinguishes compensatory interventions (such as transfers, gyms, or wellness programmes) from structurally embedded participation, arguing that only the latter can sustain long-term capability and legitimacy. Healthcare cost growth is interpreted as a resource-allocation problem arising from structural absence rather than treatable pathology alone. This work is theoretical and architectural in nature. It does not advocate a return to hardship, nor does it romanticise pre-modern conditions. Instead, it argues for the intentional design of modern participation infrastructures that embed meaningful challenge, responsibility, and constructive risk in ethically bounded, non-coercive ways. The analysis is population-level and structural, and does not address individual pathology, disability, or congenital conditions. The paper is released as an open preprint to invite interdisciplinary discussion across economics, health systems, social theory, and policy design.
