Contrived? No, I directly quoted the author of the general welfare clause in Federalist 41.
Read it again, pinhead....
For what purpose could the enumeration of particular powers be inserted, if these and all others were meant to be included in the preceding general power? Nothing is more natural nor common than first to use a general phrase, and then to explain and qualify it by a recital of particulars. But the idea of an enumeration of particulars which neither explain nor qualify the general meaning, and can have no other effect than to confound and mislead, is an absurdity, which, as we are reduced to the dilemma of charging either on the authors of the objection or on the authors of the Constitution, we must take the liberty of supposing, had not its origin with the latter....But what would have been thought of that assembly, if, attaching themselves to these general expressions, and disregarding the specifications which ascertain and limit their import, they had exercised an unlimited power of providing for the common defense and general welfare?
Since you are playing the idiot fool here, how about kindly answering Madison's rhetorical questions? Why the hell would we have an open-ended clause in the Constitution which allowed Congress to do whatever they wanted under the guise of "general welfare?" If "general welfare" was supposed to be interpreted to mean what you have claimed, there would literally not be any need for the rest of the Constitution. The general welfare clause would have pretty much covered anything and everything, nothing else would be needed. You may want to argue, what about our other rights? Well, if Congress had the unfettered power to dictate "general welfare" and define what it is, then they could simply override anything else written in the Constitution, by claiming it was for our general welfare. But the truth is, the general welfare clause is specific and enumerated in the paragraphs to follow the clause. This is not contrived, it is straight from the mouth of the man who wrote the general welfare clause, I think he is more qualified than you to tell us what it means.
