I’ve long said the Federal government forcing people to buy health insurance is the same as forcing them to purchase ketchup. I still think I’m right. The Interstate Commerce Clause doesn’t allow the federal government to do this. That’s why state government’s force buyers of vehicles to purchase car insurance. The states can, the feds can’t. FDR knew this and that’s why he made Social Security a tax.
However, there is a clever argument as to why the feds can compel people to buy health insurance and it’s not the same as forcing them to purchase ketchup. I disagree, but click on the link below for a convincing argument on the subject.
