I think people are overestimating how much doctors are paid. You can earn a lot of money as a locum but this does mean giving up a regular place of work and never being able to progress in training.
I am 4th year of working as a doctor. I have a great salary for someone my age, but my average hours are 45h/week not including routinely running over, and involves a high proportion of antisocial hours (nights, evenings, weekends) and I have to spend large amounts of my free time on portfolio, revision, extra leadership activities, training courses, meeting mandatory parts of my training in my free time, travelling more than an hour to a distant workplace I have been sent to, audit, catching up on admin etc and I spend at least £1k/year on membership, exams, courses and indemnity. Anything under 40h per week is paid as "part time" and will involve taking longer to complete training.
I'm sure there are professionals in other careers working just as hard but people don't seem to begrudge them their salaries so much?
I would earn more per hour working as a civil servant and having spent far less time and money at university. But obviously, there are a lot of other reasons to pursue medicine (academic interest, reward of "helping people", working with fantastic people within the nhs, practical, achieving "expertise" /status and financial security among them). I'm not complaining at all, still very fortunate, but pursuing medicine is a daft way to "get rich". You would be much better off in tech.
Nursing overall is a bit more family friendly, usually involves fewer hours per week (but more antisocial in junior roles), and a great flexibility to move between different specialisms and even into different HCP roles. The day to day grind of say, general adult nursing is literally backbreaking and awful (from what I have observed!). But that is not all that nursing is. If you are intelligent and academic I imagine you could do very well and reasonably quickly in a niche area - and if acting as an independent practitioner appeals these roles are only becoming easier to access. Midwifery, paediatric nursing, clinical specialists, nurse consultants, practitioners in AE - these are not mere drugdes who are told what to do by doctors! Midwives with additional training can and do carry out high risk births and procedures, unsupervised. Nurse practitioners may be the senior to whom doctors go to for advice. I am in paediatrics, the weight of ward nurses' opinions is very often just as important as mine, I literally rely on their years of experience every day - though we have different perspectives that is a good thing.
One of the key downsides of being a nurse, I would imagine, is constantly having to overcome the appalling old fashioned ideas that people have and everyone feeling "sorry for you"
It is not a a career to turn your nose up at!
