The twentieth century was an economic miracle in material terms. Yet our institutional, ethical, and cultural frameworks failed to keep pace with material transformation. We created vast wealth but allowed deep inequalities, alienation, and ecological fragility to persist. The result: global systems that are materially abundant but morally incoherent. The book develops a new paradigm: Cultural-Ethical Economics, designed to guide development policy in ways that align with human dignity, social trust, and cultural coherence. It draws upon and integrates insights from Nobel laureates and foundational economists who questioned the sufficiency of standard economic models.
