You write very well and are, I expect, very smart. So you know that I didn’t misunderstand you or that you failed to express yourself fully.
The point you made, and that I deny, is that children from state schools/less privileged backgrounds, however you want to put it, are given some leg-up or incentive by work experience in hospitals. That is nonsense.
Your children, mine and all others’ who have well-supported children with parents who care about education will be fine. If medicine is their thing, great. But no good is being done by gimmicks and stunts in hospitals.
No bright child thinks medicine is out of reach because they’ve never met a doctor.
Medical schools will take high achievers, not wishful thinkers or stupid applicants.
