By the original writing of the document, I'd have to agree with you, that they do not have this authority.
Then they do not have the authority. Period. The Constitution either is, or is not, the law of the land. Any change to one is a change to all. I, for one, have never seen an amendement to grant additional power to the federal government.
The fact is though much has changed since then, including powers the federal government has given itself and held up as constitutional in review.
Take a long hard look at that.
They granted themselves more power. Okay, I grant myself free from taxes. Problem solved.
Held up as constituional by whom? An independent civilian counsel granted constutional powers (by amendment authorizing such) to deny or autghorize powers to the feds;
or,
By a federal Supreme Court that authorized itself final arbiter of all things constitutional (Marbury vs Madison). By their ruling, the checks & balances of the triad government is now reduced by two-thirds.
Without an amendment to the Constitution, the fedreal government does not have authority to grant itself power nor to deny states theirs, nor any citizens. The Constitution is the final limitation of all federal powers, without an amendment. The amendment must be granted by, *drum roll* the states.
We the people have failed to act in our own best interest for approximately 150 years. It is our government to control, through the vote. We've failed. I'm not after changing the system, I'm for returning it to its proper place...or following the rules as prescribed under the opening charter to change the rules.
As it sits, the document is a limiter of power & does not breath.
