Grace has more than just financial privileges though. She originally amassed her online following by being conventionally attractive, white, female and genetically blessed with what was (and is still) societies perception of the ‘ideal body’ (small waist, big bum).
Financial privilege has played a part in her ability to help curate that image - expensive gym memberships, equipment, clothing, personal trainers. It also helped to show the ‘intelligent academic’ side of her online persona that makes people think she is worth listening to - private schools enabled her to gain a place at Oxford, connections that enabled her to gain an internship at IBM, and familial wealth that enabled her to task risk without consequence.
I’m not going to word this well, but essentially Grace benefits from so many privileges that even just saying she benefits from ‘financial’ privilege, misses out a very large portion of why she is so successful. We all know for a fact if she was rich, but didn’t meet societal perceptions of beauty, she wouldn’t have anywhere near the amount of success she currently has.
