The amendments already exist! More than that, the core articles already exist! The Constitutional powers delegate taxation and tariffs solely to Congress. Doing it through Executive Order is Constitutionally absurd and if Congress wasn't asleep at the wheel and criminally "Do Nothing" (especially, nothing without a Lobbyist lining your tailored suit's insides with cash like filthy lingerie) and the Judicial Branch wasn't suborned into party politics mentalities and a lot of people in both Congress and Justice weren't being hugely negligent on their sworn oaths to Protect the Constitution, there should be a lot more Checks and Balances happening right now.

This isn't about which tools should have been used at the end of the cold war. This is about which tools should have been used before the Great Depression in a country under a political party that has spent decades dismantling the tools that helped it end the Great Depression.
