Argument: Mandatory health insurance is analogous to mandatory car insurance
Paul Hsieh. "Health care in Massachusetts: a warning for America". Christian Science Monitor. September 30, 2009: "Just as drivers must purchase auto insurance, the medical system of the future would put responsibility for health coverage first and foremost on every adult.
For the vast majority of Americans who have health insurance, the change would mean little more than submitting a form with their tax returns proving that the plan they carry meets certain minimum standards. Many of the nation's 47 million uninsured people, however, would be required to purchase a health policy or face financial penalties, though waivers or discounts would be provided for lower-income Americans."
