What, exactly, is the problem here?

Something, something, mumble, mumble:

A giant American healthcare group will employ its own doctors when it opens its first hospital in Britain in a move that experts have warned could result in a rush of medics permanently moving to the private sector.

....

Experts warned that the recruitment could add to NHS workforce pressures that reached breaking point during the pandemic. If the model is a success it could mean an exodus of NHS-trained doctors moving permanently to the private sector, they say.

The government takes upon itself the job of planning for, then training, those required to deliver health care in the UK. Whether they then work for the NHS or the Cleveland Clinic wouldn’t seem to matter. They are delivering health care in the UK off the back of the training, no?

Any why would we worry about a non-profit, one that runs the finest cardiology department in the US, in fact one of the finest hospitals in that country, organising some of the health care in London? The very complaint is that it will be British people doing health care for British people in Britain. Which does seem to be a very odd thing to be worrying about.
