But authorized or not most Americans WANT social security. I doubt the supreme court is ever going to declare it unconstitutional, because the backlash would be huge. I think this is why we have Amendments to the Constitution. The Congress and the Courts have to respect public desires or else they actually amend the Constitution.

So the "founding father's original meaning" position is pretty silly. Amending the Constitution is right there in the Constitution itself. Many of those amendments are complete reversals of the founders positions.
