I read a post ages ago that explained that Carrie makes out like her dad’s job wasn’t great but he worked at Kodak and they were actually very well paid there. Yes they may have had to save to pay for the holidays but they were able to save enough to go every year. Most people can just about afford to go once in their life and that’s with saving and paying off the holiday over time.
Also Carrie doing theatre regularly as a child would cost her parents a lot of time and money taking her into London several times a week. Plus their dad knew one of the Sherman brothers right? I feel like there’s a lot more to her childhood and her parents than we know about. Her upbringing was very very comfortable and she either doesn’t realise or wants to hide it to be relatable / that Carrie thing of wanting to be oppressed when she’s not.
I've always thought Carrie has a very narrow view of privilege and how it can show up, and the Sherman brothers stuff is an example of that. Even if they weren't the richest family in the world, having that kind of family friend
is a privilege when you want to work in theatre. As is her whiteness, her thinness, being able-bodied, or even living in/close to London. On top of that, her brother being famous helped her enormously with her YouTube channel. Yes, it took her producing content to keep it going, but she initially had the attention because she's a Fletcher. None of these things are inherently bad, and people with more than that do less in life than she has, but not acknowledging and accepting it is quite immature.
Also, she can say she's working class until the cows come home but being working class is not shorthand for poor. While some definitions of class relate solely to the type of work a person does (like manual labour), it's also fair to define class by income. My dad worked an office job when we were kids, but we were poor as
duck because it doesn't matter what type of job you have if it pays terribly. The fact her dad worked at Kodak is meaningless if it paid well.
If she's desperate to be disadvantaged, then she could open up about how her brother's career and name follows her around. How she finds it hard for people to see her as her own person outside of that. Or even about her mental health struggles and how they can impact things (I remember her saying a few years ago that she was on antidepressants).
