I think that "the powers that be" in the past were far less likely to be challenged, that many incidences of poor practice existed, but these days both the mainstream press and Social Media bring far more into the light, and far many more people feel empowered to stand up and shout.
This is often, even usually for the good, but sometimes demands are made that sadly are just not realistic. It is realistic of course, to call to account and to examine "why" so it is not repeated.

Real life example - Can my DGD go on the Ormond Street Trial for very severe epilepsy - maybe involving a quite major brain operation - when so many want it? Who will pay expenses if you don't live in London, and so on. How do you weigh this against proper end of life treatment? We can't.
