“Comprehensive health insurance is such an ingrained element of our thinking, we forget that its rise to dominance is relatively recent. Modern group health insurance was introduced in 1929, and employer-based insurance began to blossom during World War II, when wage freezes prompted employers to expand other benefits as a way of attracting workers. Still, as late as 1954, only a minority of Americans had health insurance. That’s when Congress passed a law making employer contributions to employee health plans tax-deductible without making the resulting benefits taxable to employees. This seemingly minor tax benefit not only encouraged the spread of catastrophic insurance, but had the accidental effect of making employer-funded health insurance the most affordable option (after taxes) for financing pretty much any type of health care. There was nothing natural or inevitable about the way our system developed: employer-based, comprehensive insurance crowded out alternative methods of paying for health-care expenses only because of a poorly considered tax benefit passed half a century ago. ”
