Health insurance originated in the industrialized nations of Europe,
emerged in the United States in the early 20th century, and spread through
US employers who sought to attract workers with this benefit. Health insurance
was designed to protect workers against the catastrophic costs of medical
care and create an incentive for individuals to pursue cost-effective preventive
services that would keep them healthy enough to remain on the job.1 In 1965, the government introduced Medicare and Medicaid
to extend health insurance coverage to elderly and some poor persons. However,
for a variety of reasons, the United States remains the only industrialized
nation without universal health insurance coverage.
