I used to work in the NHS and Salz is completely right, it is badly managed.
I don't read the DM , so I have no idea what their latest rant is and almost certainly wouldn't agree with it, but I think you undermine your own argument, Draylon, when you mention the "top-of-their-game private industry managers/big shots/profit generating people and consultancies". The idea that MBAs from private sector businesses should be able to apply the values and methods of the marketplace to the particular needs and goals of fields such as health and social care is just flawed. You can't put things like fear, pain, kindness, dignity or common sense into a spreadsheet, and doing a good job doesn't translate into a healthy bottom line. Arguably, managerialism doesn't even generate efficiency in the private sector but certainly it is the wrong answer where a civilised public sector is concerned.
To my mind, one of the problems is that only those on the inside have a decent grasp of the issues and how they might be fixed, and by the time you are in that position you are exhausted by your workload and too demoralised to do anything but get through your own shitty day. (That is certainly how I felt anyway.) But the other problem of course is chronic underfunding. If the UK spent the average (mean) % of GDP per capita for comparable western industrialised countries, it would release enough funding into the NHS to end all healthcare rationing, all geography-based inequality of access and all waiting lists. And all free at the point of access. How anyone thinks copying a US-style system of insurance companies and marketised treatment providers is a better solution to this situation is anyone's guess. (Or actually no one with any influence does, they are just keeping an eye on their stock portfolios.)
Sorry, bit of a rant there. This is a sore topic.
Anyway, as Salz says, all this is beside the point. The idea is that anyone leaving the UK post-Brexit would retain their citizenship in order to access the NHS is hilarious. The same mandateless government (election expenses, anyone?) who brought you the waking nightmare that is Brexit has already all but dismantled the NHS and will undoubtedly finish the job before long.
And yes, all the doctors are going to NZ, Oz, Canada and SA.
