First I'd like to clear up what I believe to be a common misinterpretation of this song: that the singer is a girl who comes from humble beginnings that dreams of unattainable riches. However, realizing such luxury can't be had, learns to be content with what she has and to simply fantasize about the lifestyles of the rich and famous.
This sort of makes sense, but I would argue that the singer is really attacking the materialistic set of values that are pushed by both society and mainstream media. She critiques "every song" and "everybody" by listing off stereotypical glamorous, corporate objects and essentially accuses them of causing people to be "caught up in a love affair" with material goods.
What does this sound like? Commodity fetishism. The song opens with, "I've never seen a diamond in the flesh." Already in the first line the singer establishes the human quality that is transferred to objects in modern society. And what does a diamond typically communicate on behalf of its wearer? Wealth, power, luxury.
This isn't even the most obvious example of commodity fetishism in the song. "But every song is like gold teeth, Grey Goose, tripping in the bathroom, [etc.]" and "but everybody's like Cristal, Maybach, diamonds on your time piece, jet planes, islands, tigers on a gold leash." While they phrase "is like" isn't the easiest to understand, here I took it as "everybody values these objects" because the media (songs) and other people (everybody) tells us to. The singer tries to distance herself from people who have started to develop relationships (i.e. "love affairs") with objects and the lifestyles supposedly attributed to them, rather than other people. Hence, she uses "we" to distinguish between those who prioritize objects ("us") and those who prioritize others ("them").
The song then turns from comparing these priority preferences to a request for empowerment. The singer asks to become the "ruler" and the "queen bee." She is looking to shift the power that has been transferred onto these objects and symbols of luxury back onto herself—a person. With it comes a shift of priority back to each other rather than what each of us has.
