Oh yeah, the aesthetics of Beth's spiral are absolutely a reflection of her economic status and the culture she's living in as well as her neurotype, you're very right to bring that up. She inherits an entire house (well, for a while), complete with a grand piano. Her wealth grants her the ability to spend days upon days drinking and taking pills without any social or financial consequence -- she also doesn't have to worry about how to fund the pills and booze. Great point.
