I do agree the NHS is really struggling right now, and there has been a lot of short-sightedness in terms of staff recruitment (both doctors and nurses). A lot of out of hours services have been shut down or are not 24 hours, which doesn't help reduce the strain on A and E. The lack of GP appointments also doesn't help as people's complaints may get worse before they can be seen, or they may feel they can't wait for an appointment to be available.
I will admit to having recently gone to A and E for something probably not A and E worthy, but despite living in a major city, there were no out of hours services available and I was in a huge amount of pain on a Sunday and really felt unable to wait 24 hours to see a doctor (assuming I could even get an appointment on the Monday). I expected to have a long wait, but was actually in and out within 3 hours.
IMO, we could easily fund a proper NHS still, if that was our priority as a country. If health and social care was also properly funded, that would help massively, as it would take the strain away from hospitals and mean that less people got into crisis in the first place. There might also be some places for bringing in charges such as charges for missed appointments or fines for violence against staff.
I do think that the tories have been very successful in making the narrative one of "we can't possibly pay for X, Y or Z", but I don't think that's true. If we weren't wasting billions of pounds on Brexit, for example, and if we decided on our priorities as a country, we absolutely could still fund the NHS, especially if there was more joined up thinking, rather than just slashing everything to the bone and leaving the NHS to pick up the pieces.
