yawn. . no it isn't, this is the same ole flawed argument. Follow this simple logic so I don't have to go digging through old posts for quotes. They included the phrase "common defence" as well as "general Welfare" , yet they went on to list specific powers for providing defense. IF they meant "do whatever you deem necessary to provide a national defense" then why would they go on to list specifics? They wouldn't, the same is true for the "general Welfare" clause. If they meant for Congress to do anything the present body thinks is in the best interests of the nation, then why did they list non-defense related powers after that clause? Because that isn't what they meant, and they laid out specific powers.Those enumerated powers including "provid[ing] for the . . . general Welfare . . .." Whether it is limited to defense and highways and so forth is a matter of interpretation.
The first sentence of the section is explanatory and the powers that follow are definitive.
There are also many quotes and writings from the Founders that prove this to be the case. Again, if Congress/fed govt wants more authority for social programs etc, then they should do it the right way which is by Amending the Constitution. Since they have gotten away with doing as the please without following the proper procedure, they don't bother and probably never will unless we elect the right people. Which won't happen as long as voters remain ignorant and/or pretend the above isn't the case and the "general welfare" clause is open to 'interpretation'.
