Now that Republicans have withdrawn Mr. Ryan’s bill from consideration, attention shifts to what comes next. In an earlier column, I suggested that Mr. Trump has the political leverage, which President Obama did not, to jettison the traditional Republican approach in favor of a form of the single-payer health care that most other countries use. According to Physicians for a National Health Program, an advocacy group, “Single-payer national health insurance, also known as ‘Medicare for all,’ is a system in which a single public or quasi-public agency organizes health care financing, but the delivery of care remains largely in private hands.” Christopher Ruddy, a friend and adviser of the president, recently urged him to consider this option.
Many Republicans who want to diminish government’s role in health care view the single-payer approach with disdain. But Mr. Trump often seems to take pleasure in being unpredictable, and since he will offend people no matter which way he turns, he may want to consider why liberals and conservatives in many other countries have embraced the single-payer approach.
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.
