Since the early nineteen-eighties, by contrast, financial blowups have proliferated and living standards have stagnated. Is this coincidence? For a long time, economists and policymakers have accepted the financial industry’s appraisal of its own worth, ignoring the market failures and other pathologies that plague it.
