Mandated Health insurance isn't the same as Mandated Car insurance because Car Insurance is required only if you take an action, owning, and operating a car or motorcycle. Mandated Health insurance is arguably unconstitutional in the U.S because it is the regulation of inaction which isn't what the Interstate Commerce Clause of the U.S Constitution gives Congress the right to regulate. That Clause gives the U.S Congress the right, and duty to regulate commerce across state lines, and commerce is economic action, not inaction. Simply living would be considered inaction, not an action therefore Congress mandating health insurance is unconstitutional in the U.S if that position is held. @Orathaic: That is what would be called a Good Samaritanism law which has never been legally argued for in the U.S, though I believe it exists in some European countries in some matters. I would argue that trying to enforce ethical behavior in general terms is a. beyond the scope of what any government's powers should be, and b. is unrealistic to enforce anyway. Now I believe that you can make the distinction between Good Samaritanism and Minimally Decent Samaritanism, and that no one should fall below the standard of being minimally decent. An example is it appears a seriously injured person is lying on the side of the road you are driving on, a Good Samaritan would stop and help the person and call an ambulance, a minimally decent Samaritan would call emergency personnel, and continue on. Now certainly not calling 911 would be monstrously indecent, but you shouldn't be obligated to get out, and help the person either. In the case of being required to pay for health insurance for the poor I would argue that is beyond even Good Samaritanism, and is heroic in action, and therefore can't be enforced, and while it should be highly praised it shouldn't be required or expected of people.
