If you want to claim this is “enlightened” then we’d need to define what we’re talking about.
The first song doesn’t express any kind of working class solidarity. It merely expresses pride in how hard mom and pop worked, within the context of classic American conservative morality.
Yeah, I don't think you can meaningfully contrast Coal Miner's Daughter with Rich Men North of Richmond (going by looking at lyrics here, I'm listening to other music right now and cba to spend half my evening listening to country). In fact, if anything Oliver Anthony's lyrics have more explicit class conflict in them: "I've been sellin' my soul, workin' all day/Overtime hours for bullshit pay.../These rich men north of Richmond/Lord knows they all just wanna have total control". Obviously it's possible for that to exist within the same song as the more reactionary stuff.
I'd also be wary about conflating Anthony with Aldean too much - Anthony's song seems more like, how do I phrase this without sounding like some patronising Marxist who has All The Correct Ideas, a relatively spontaneous expression of a worldview that has some contradictory aspects, Aldean seems more like a deliberate and calculated appeal to rightwing ideology.
Without wanting to romanticise country's past too much, I think that, while Anthony's pride in hard work fits neatly within the tradition including some of the stuff dlr posted as enlightened above, Aldean's lyrics about "cuss out a cop, spit in his face" really is a break from the work of classic outlaw country artists, who would've been more likely to sing about cussing at cops than why you shouldn't do that.
Also: Rob Ray had a thoughtful post about this song over on the Trump thread, and
there's a whole thread of left-wing country here. I remember really liking
this article about Lil Nas X and the ideas of hiphop and country.
Finally, it's weird that I can't think of any musicians called Culture War or Culture Wars. I'm sure someone must've used the name at some point, but I've never heard of them. Culture Shock, Alien Kulture, Resistant Culture, but no Culture War.
