I don’t dispute your point about nurses and housekeeping, but when people talk about underpaid doctors, they’re not talking about the consultants with Teslas, they’re talking about the junior doctors with a mountain of student debt. They may earn more than nurses, but after 7 years of accumulating debt they kind of need it.
Sure, the rich ones whose mummy and daddy paid for it are fine, but becoming a doctor for ordinary people in this country is pretty thankless and rough, so unless we want doctors to just be toffs we do need to offer compensation on the assumption they won’t be rich going in.
Again, not disputing that nurses deserve better too, but there’s no need to disparage other groups to make that point.
