BTW - in terms of the state of the NHS - this assessment by the Kings Fund in 2018 found the following:
Key findings
• Overall, our analysis shows that the NHS performs neither as well as its supporters sometimes claim nor as badly as its critics often allege. Compared with health systems in similar countries, it has some significant strengths but also some notable weaknesses.
• Its main weakness is health care outcomes. The UK appears to perform less well than similar countries on the overall rate at which people die when successful medical care could have saved their lives.
• Although the gap has closed over the last decade for stroke and several forms of cancer, the mortality rate in the UK among people treated for some of the biggest causes of death, including cancer, heart attacks and stroke, is higher than average among comparable countries. The UK also has high rates of child mortality around birth.
• Among its strengths, the NHS does better than health systems in comparable countries at protecting people from heavy financial costs when they are ill. People in the UK are also less likely than in other countries to be put off from seeking medical help due to costs.
• Waiting times for treatment in the UK appear to be roughly in line with those of similar countries and patient experience generally compares well.
• While data is limited, the NHS seems to be relatively efficient, with low administrative costs and high use of cheaper generic medicines.
• The NHS appears to perform well in managing certain long-term illnesses, including diabetes.
• Health care spending in the UK is slightly lower than the average in comparable countries, both in terms of the proportion of national income spent on health care and in terms of spending per person.
• The UK has markedly fewer doctors and nurses than similar countries, relative to the size of its population, and fewer CT scanners and MRI machines.
So what the OP is suggesting on this thread is to damage the one aspect of NHS provision which is its primary strength - in the accessibility of healthcare, and subsequently in the way it manages long term conditions like diabetes where accessibility is crucial.
Note that we've traditionally spent less on healthcare than other comparable countries, despite the UK population being fatter and less healthy than most European populations. (BTW, recent estimates of NHS spending in the UK have been distorted by the inclusion of pandemic spending in the totals).
Would also add, this report is from 2018, following 8 years of underspending during austerity, where the growth of healthcare spend didn't keep pace with the growing cost of treatment or of an ageing population.
