The founding fathers may have written the words, but SCOTUS is tasked with interpreting the document, and there is no appeal from their decision.
Wrong. Congress has two options. They can either write another law that is worded differently and hope that the Supreme Court lets it stand, or they can pass a constitutional amendment. If a constitutional amendment is passed, the Supreme Court has no way to overturn it.
The people, of course, can override the SCOTUS anytime they choose via simple non-compliance..
You are conveniently forgetting the process for having an Amendment ratified and added to the constitution.
The amendment must be passed by a 2/3 majority in both the house and senate. Following that, 3/4 of the state legislatures must approve the amendment. No changes may be made to the amendment once passed by the US Legislature. The Constitution does not stipulate a time limit but seven years has been accepted as a reasonable time.
Meanwhile, back at the ranch, the easiest and best solution is to eliminate the Federal Minimum Wage. If any of the states wish to have a minimum wage, for their state, they are welcome to see how that works for their state.
