Part of the appeal of Medicare for all is that single-payer systems reduce financial incentives that generate waste and abuse. Mr. Ryan insisted that by relegating health care to private insurers, competition would lead to lower prices and higher quality. Economic theory tells us that this is a reasonable expectation when certain conditions are met. A crucial one is that buyers must be able to compare the quality of offerings of different sellers. In practice, however, people have little knowledge of the treatment options for the various maladies they might suffer, and policy language describing insurance coverage is notoriously complex and technical. Consumers simply cannot make informed quality comparisons in this industry.
Consider, too, the mutually offsetting expenditures on competitive advertising and other promotional efforts of private insurers, which can exceed 15 percent of total revenue. Single-payer plans like Medicare spend nothing on competitive advertising (although here, also, we see such expenditures by supplemental insurers).
According to the Kaiser Family Foundation, administrative costs in Medicare are only about 2 percent of total operating expenditures, less than one-sixth of the rate estimated for the private insurance industry. This difference does not mean that private insurers are evil. It’s a simple consequence of a difference in the relevant economic incentives.
American health care outlays per capita in 2015 were more than twice the average of those in the 35 advanced countries that make up the Organization for Economic Cooperation and Development. Yet despite that spending difference, the system in the United States delivers significantly less favorable outcomes on measures like longevity and the incidence of chronic illness.
