Universal Health Care
The U.S.is the only "wealthy" industrialized nation that does not insure its residents with some form of universal health care, although the governmental health care system (including Medicare, Medicaid, SCHIP, and TRICARE) does cover more than a quarter if US residents.
In the absence of a universal health care system that covers all Americans, about 85% of Americans have some form of health insurance coverage, including individual health insurance, employer-sponsored health coverage, and the government sponsored programs mentioned above.
In lieu of a national system, the state of Massachusetts has enacted a state-wide requirement that all MA residents maintain health insurance coverage.
Nationally nearly 47 million Americans go without health insurance each year, which frankly is a tremendous risk. Even though the US doesn't have a universal health care system that guarantees you health insurance free of charge, there are affordable health insurance options available.
