10th Amendment-protected state powers are not immune to social Darwinism. I suppose that we can always remove cities from the map and stars from the flag for cities and states that implode.
I’m not sure that the Tenth Amendment covers this kind of behavior, but the Guarantee Clause of Article 4 Section 4, which states that the federal government has to “guarantee to every State in this Union a Republican Form of Government”, I interpret that at least as an obligation to prevent states from instituting a socialistic form of government; but seeing as how the federal government has been itself turned socialist for decades, it is more inclined to influence the states to go socialist as it has been doing.
