The Patient Protection and Affordable Care Act, 124 Stat. 119, grew out of a long history of failed health insurance reform. In the 1990s, several States began experimenting with ways to expand people’s access to coverage. One common approach was to impose a pair of insurance market regulations—a “guaranteed issue” requirement, which barred insurers from denying coverage to any person because of his health, and a “community rating” requirement, which barred insurers from charging a person higher premiums for the same reason. Together, those requirements were designed to ensure that anyone who wanted to buy health insurance could do so. The guaranteed issue and community rating requirements achieved that goal, but they had an unintended consequence: They encouraged people to wait until they got sick to buy insurance. Why buy insurance coverage when you are healthy, if you can buy the same coverage for the same price when you become ill? This consequence—known as "adverse selection"—led to a second: Insurers were forced to increase premiums to account for the fact that, more and more, it was the sick rather than the healthy who were buying insurance. And that consequence fed back into the first: As the cost of insurance rose, even more people waited until they became ill to buy it.

This led to an economic "death spiral." As premiums rose higher and higher, and the number of people buying insurance sank lower and lower, insurers began to leave the market entirely. As a result, the number of people
