In 1794, when Congress appropriated $15,000 to assist some French refugees, James Madison, the father of our Constitution, stood on the floor of the House to object, saying, "I cannot undertake to lay my finger on that article of the Constitution which granted a right to Congress of expending, on objects of benevolence, the money of their constituents." Did James Madison miss something in the Constitution?
You might answer, "He forgot the general welfare clause." No, he had that covered, saying, "If Congress can do whatever in their discretion can be done by money, and will promote the General Welfare, the Government is no longer a limited one, possessing enumerated powers, but an indefinite one."
If we accept the value of self-ownership, it is clear that most of what Congress does is clearly immoral. If this is bothersome, there are two ways around my argument. The first is to deny the implications of self-ownership. The second is to ask, as Speaker Nancy Pelosi did when asked about the constitutionality of Obamacare, "Are you serious? Are you serious?"
