In The New Republic, Harvard Law Professor Einer Elhauge writes that -- contrary to those arguing for the unconstitutionality of the Affordable Care Act -- the historical evidence shows that many of those who participated in the framing of the U.S. Constitution approved of the idea of an individual health-care mandate. From Elhauge's piece:
The founding fathers, it turns out, passed several mandates of their own. In 1790, the very first Congress—which incidentally included 20 framers—passed a law that included a mandate: namely, a requirement that ship owners buy medical insurance for their seamen. This law was then signed by another framer: President George Washington. That’s right, the father of our country had no difficulty imposing a health insurance mandate...
In 1798, Congress addressed the problem that the employer mandate to buy medical insurance for seamen covered drugs and physician services but not hospital stays. And you know what this Congress, with five framers serving in it, did? It enacted a federal law requiring the seamen to buy hospital insurance for themselves. That’s right, Congress enacted an individual mandate requiring the purchase of health insurance. And this act was signed by another framer, President John Adams.
Not only did most framers support these federal mandates... but there is no evidence that any of the few framers who voted against these mandates ever objected on constitutional grounds. Presumably one would have done so if there was some unstated original understanding that such federal mandates were unconstitutional. Moreover, no one thought these past purchase mandates were problematic enough to challenge legally.
