It is also a job that very few people are capable of doing
I also don't believe this. It's a job that very few people are capable of getting on to the training course for. The majority of the consultants I work with are excellent^^ and have been in the job 30 or 40-odd years. They got a mixture of A-Level results, but most were in the BBC, BCC, CCC range. They freely admit they'd never get in to do medicine these days.
The retention crisis is partly because we're now choosing the wrong people for the course. Academically brilliant, but little in the way of life experience or (often) common sense. They have no 'street smarts' because they're often from very privileged backgrounds, and have been spoon fed at private schools from an early age. Often they come from wealthy backgrounds and this gives them choices. If they qualify and find that they hate it or can't cope with the pressure, their backgrounds mean they can just up sticks and leave, and retrain as something else. I don't blame them. A fair few do this now, Many more so than when I trained.
I came from a working class background. I happen to love my job, but if I'd have hated it, I'd still have stuck it out as I'd got so much debt I'd have had no choice!
We need to be selecting Med students differently these days. We need to forget attracting triple A* students, and focus more on those with the right personal characteristics and a heavy dose of resilience. Having worked in A&E, I would argue that a black belt in Karate and a job working behind a bar in a rough part of town are far more useful attributes than Grade 8 piano, but we still insist on choosing students with the latter 🤦🏻
