Chubfuddler, for me it's more that she isn't really making money from her medical training. I'm more wondering about the psychology of someone who would abandon something into which she has put such time, effort, intelligence, money, to do something which can be performed by non-medically trained people.
If, after all, she followed the normal route and went on training in a specialism, she would also eventually make significant money as a consultant. She presumably has the option of combining her interests, and actually training as a plastic surgeon or dermatologist, but she's turning her back on that, which looks awfully like being all about making a quick buck from insecure people who aren't ill.
I also think that taking the Hippocratic oath sits uneasily with using your training to 'add value' to doing unnecessary, ethically dubious cosmetic work.
I would have agreed with you about Neckbeard using his dead father for brownie points earlier in the series, but I think it emerged that he's actually completely in earnest about it. I thought that bit about his father being quite so obsessed with him becoming a pro footballer was sad, actually. He seems joyless and damaged.
