There's no simple answer. Social care is broken, meaning a lot of bed blocking by medically fit older people who cannot be discharged because no suitable care package can be put in place to support them in their own homes. Care home bed numbers continue to plummet and a lot of care homes are not the kind of place you would want your loved one to end up in. Some are great. All are expensive.
Add that to an ageing population, medical advances keeping people alive, but in need of a lot of ongoing care and treatment, who would have just died even a few decades ago, hopeless lack of funding, hopeless state of general practice, bed cutting, billions wasted on NHS reorganisation (I used to work for the NHS - within the space of a handful of years our overarching organisation had gone through 4 mergers/re-organisations at god knows what cost - certainly the quality of patient care did not improve one iota in fact just the opposite).
Those on the front line do their best but it's little more than fire fighting sadly. I have a partner who works for social care and a DD who is a nurse and they are swamped.
