Yawn...
Are you completely dismissing *any* meaning from the general welfare phrase in our Constitution, or are you one of the last 3 intellectually honest libertarians willing to actually post the *specific* meaning that you ascribe to the phrase "general welfare"?
And when after painstakingly listing the powers granted to the central government (such as provide post roads, coining money, etc.) then saying "To make all laws which shall be necessary and proper for carrying into execution the foregoing powers ", did you think the foregoing powers means all the ones specifically listed and any other power under the sun? I don't think so either. Maybe you should reconsider.
I have not asserted an inerpretation of its meaning, you have(albeit by insinuation). I have refuted your implication by pointing out that the meaning of the words you quoted is not as you imply.
"General welfare of the United States" does not equal making sure Jane Doe gets a check every month. In fact, it does not even say "general welfare of the People of the United States."
Just the welfare(meaning well-being) of the nation, not "welfare" as recently redefined to mean money for poor people. The word didn't even have that meaning when the document was composed.
If you want a hint, both this and the interstate commerce clause are more appropriately applicable to things like interstate highways and maybe meteorological sevices, things like that. Things which contribute to the general welfare of the nation.
