What Should My Advice To Her Be?

Hello There Learned People, Good Morning! I'm asking this question on behalf of a beloved friend who's a Psycho-Oncologist. She's great at what she's been doing and somehow, it's been 5 years and I am unable to see her grow financially. She's working with NGOs and Indian Cancer Society and helps her cases and indeed has been doing an extremely noble job but in my opinion, her domain, her knowledge and her skill-set is under appreciated where deserving a good fat salary is concerned. She is the sole breadwinner for her family and has responsibilities on her shoulders and whenever we've discussed this subject, she has mentioned that she'd want to move on and switch jobs and continue learning and helping her cases but is unsure of how she'd be able to move ahead. She feels she will be abandoning her team and her people and her cases. I am not from this domain and hence I sincerely request you good souls to help me out here. I'll be truly grateful to your golden pieces of advice. Cheers!
