Market incentives in capitalist economies and public health requirements are contradictory. In the COVID-19 pandemic, market-rewarded self-interested behavior has been exposed as a source of mortality and morbidity. Profit-motivated behaviors can keep people from accessing necessities for health thereby harming individuals and possibly damaging population health. The profit motive can also undermine healthcare system capacity by maldistributing goods that are inputs to healthcare. Furthermore, because profit-seeking is economically rational in capitalism, capitalist imperatives may be incompatible with public health. The ways markets misallocate resources provide a rationale for state responsibility for health, which is a public good.
