I thought this at first but after reading the lyrics instead of listening I don’t really think he is complaining about rich people explicitly. “rich men north of richmond” is just a poetic way to say politicians, imo, and so the song seems just anti-government. I guess you could consider the first part about workin all day has working class vibes, but that isn’t a condemnation of rich people it’s just talking about how life sucks right now.
