We certainly all agree we need to break up the control of the political elite, and the ruling class who really wield the power in the shadows who control the politicians.
So just a couple of things to consider:
1) The Federal Government already does not abide by the Constitution, and worse, have subverted it in numerous ways already:
ie, 16th Amendment on Income Tax, and the Federal Reserve System Act - both in 1913. The Federal Reserve System is none of those - it delegated Congress's money responsibilities to Central Bankers and created a printing press to finance government, with income tax in place to make sure it's paid for by us. Prior, government worked off of tariffs, government bonds - people voted with their money.
ie,17th Amendment on Direct Election of Senators, which subverted the State's representation in Congress to preserve States rights. Had the Senate for the last 100+ years done their job in defending State sovereignty vs campaigning for popular votes and special interests, Federal overreach would have been kept in check. Also, 1913.
ie, Trade Promotion Authority, aka Fast Track, which subverted Congress' Article 1, Section 8, Clause 31 authority “To regulate commerce with foreign Nations”, and granted that to the Executive Branch. See: [[Trade Promotion Authority]]
ie, Foreign Aid, which wasn't even a thing until we began providing foreign aid after World War II, with the implementation of the Marshall Plan in 1948.
ie, Declarations of War, last time was 1941, and of course since then the U.S. has engaged in military conflicts through other means, such as authorizations for the use of military force or other resolutions, rather than formal declarations of war.
2) Is the Constitution the problem? Or is it the politicians who are not obeying it the problem?
3) Is adding amendments going to address the issues already provided for in the Constitution but are either subverted not obeyed?
4) Is there a risk of unintended consequences, or that the well-meaning process gets hijacked by subversive elements already operating in plain sight who have subverted the Constitution through other means already? See: [[Council on Foreign Relations]]
