The basic structure of the American health care system, in which most people have private insurance through their jobs, might seem historically inevitable, consistent with the capitalistic, individualist ethos of the nation.
In truth, it was hardly preordained. In fact, the system is largely a result of one event, World War II, and the wage freezes and tax policy that emerged because of it. Unfortunately, what made sense then may not make as much right now.
Well into the 20th century, there just wasn’t much need for health insurance. There wasn’t much health care to buy. But as doctors and hospitals learned how to do more, there was real money to be made. In 1929, a bunch of hospitals in Texas joined up and formed an insurance plan called Blue Cross to help people buy their services. Doctors didn’t like the idea of hospitals being in charge, so some in California created their own plan in 1939, which they called Blue Shield. As the plans spread, many would purchase Blue Cross for hospital services, and Blue Shield for physician services, until they merged to form Blue Cross and Blue Shield in 1982.
Most insurance in the first half of the 20th century was bought privately, but few people wanted it. Things changed during World War II.
In 1942, with so many eligible workers diverted to military service, the nation was facing a severe labor shortage. Economists feared that businesses would keep raising salaries to compete for workers, and that inflation would spiral out of control as the country came out of the Depression.
