Can Congress, in accordance with our Constitution, require us to buy health insurance, and penalize us if we refuse? Even though the Constitution delegates the federal government certain powers, the others being retained by the States (via the 10th Amendment)?
A columnist at the Washington Post says it's a no-brainer:
"In the 1942 case of Wickard v. Filburn, the justices ruled that even though an activity may "be local and though it may not be regarded as commerce, it may still, whatever its nature, be reached by Congress if it exerts a substantial economic effect on interstate commerce."
"Thus, the court said, Congress was entitled to tell Roscoe Filburn how much wheat he could grow to feed his own chickens. Surely, then, Congress could require Filburn's grandson to buy health insurance."
