Nothing else matters in a Constitutional debate other than the words in the Constitution. The phrase "general welfare" means allowing citizens to enjoy peace and prosperity or the ordinary blessings of society and civil government...nothing more and nothing less. It does not grant any powers to the federal government.
I was merely posting the opinion of what one of the framers of the Constitution, for dramatic effect.
The Founding Fathers wisely worded the Constitution in very specific and restrictive terms and were clear that it was meant to be taken literally and that the federal government was to have zero implied powers and could only gain powers through the amendment process.
This is cut, dry, and unlike yours....accurate.
