Let's go back in time, say the winter of 1993. I had recently moved in with my new girlfriend,, who was a student nurse at Pinderfields Hospital in Wakefield. Yet despite living with her we rarely saw each other, because even though she was just a student nurse she was expected to regularly pull 18 hour shifts because there was a massive shortfall of staff. And she was one of the "lucky" ones, junior doctors there often spent up to 72 hours on site, literally taking naps in empty offices when they could. The corridors of the hospital were often filled with patients waiting to be seen, and people often died as a result. And Pinderfields Hospital was far from the worst performing hospital in the UK.
The NHS is not a charity, it is not a stricken puppy or a poorly child. It is a government run, publicly funded service. And it has been chronically underfunded and terribly managed for decades. It's response to covid was terrible, it was more or less shut down to everything but covid. Indeed my better half had to wait months to be tested and receive results to what her GP believed might have been ovarian cancer. Thankfully when the results finally came through she was negative, but that delay could have been fatal had she been positive. And many, many people had similar experiences. Indeed many people have died because the NHS wasn't prepared to deal with them.
Right now covid is not the cause of the NHS problems, it is the severe backlog of patients who have been ignored for 18 months. So if you think it is heartless to blame politicians and NHS bosses for the terrible decisions so be it. But I think it is worse to let them off the hook.
