What doesn't make sense is that what keeps UK trained doctors working within the UK?

It's goodwill. They could improve their lives immensely with a move to Australia, and New Zealand. If they are willing to do another round of exams on par with their finals they can go to Canada and the US.

That's what it means when I say it's staffed by goodwill.

Some stay due to goodwill, but others are surely just inertia; selling your house, moving kids out of school, leaving friends and family behind, etc.
