Compare the inflation rates between Alabama and Argentina. Alabama is significantly better. Compare the GDP per capita. Oh that is right, Alabama is better. Is there any spot where Argentina is more stable or prosperous than Alabama?
Sure. Because even as the ~weakest part of the US, it's still part of the US and gets to ride that tide.
Fully severed and deprived of any US privilege, it's leadership could quickly face any number of newsworthy options like mass die offs due to minimal health care and low vaccination rates, being overthrown by a Latin / South American interest or dying in a bloody coup because they couldn't muster enough resources to complete their 10000 Sweltering Gulags plan fast enough.
Do you have any proof to anything you said? It just sounds like you hate the people of Alabama and are fantasizing about how dystopian it would be more than anything based in reality.
