Heres the thing I don’t think there ever has been a unified American culture, as soon as assholes started to step off this boats there was already inevitable cultural divergences happening, for example the Massachusetts Puritans who were theocratically driven, the Marylanders who were driven by proto-secular ideals, and Valirginians who were economically driven. While the Mid-Atlandit and New England cultures did reconverge over the last century of so, Coastal Southern especially the rural variants is still noticeably divergent from the rest of the east coast.
Also I’m just gonna note that everything you listed is caused by top down economic pressures that are arguably on the verge of collapse. One of the things you have to factor into your analysis of American cultures is that all of them are subject to federal level pressures meaning that even the most communal cultures for example still have to participate in capitalism due to say taxes since that’s basically the only way to earn cash. I suspect once the feds collapse you’ll see a springtime of nations and the possible death of the Pan American amalgam culture, at least within the first 20 years or so.





Well that and also a lot of us North American ones can trace our culture back to the Unions of old and to a more abstract extent a Scottish striker group who were also called Rednecks, so we have that to take pride in really it’s mostly the boomers and Gen X who tarnished our name silent, greatest, and lost were proper feral and militant against the corporations at times. But yeah Redneckism is basically the inevitable end result of people being too smart, unwise, and not having enough money to do a job proper proper.
