LOL.....that's funny...."they simply didn't think of it". Your interpretation of General Welfare isn't constitutional. It didn't mean the government should pay insurance premiums for people. I do agree with you that the founders "simply didn't think of it". They didn't think of it because that's not what the "general welfare clause" was intended for. You lefties are continually trying to rewrite the Constitution. Funny stuff.
You make it seem like the right wing is simply, clueless and Causeless.
The common Defense is not the common Offense or general Warfare.
The general welfare clause is general, not major or specific or common.
