This is nonsense. Absolute "I have drank the coolaid and have to tell everyone how very nice it tastes" total, utter bollocks.
I am someone who had a VERY close relative living in one of those institutions who was safe and happy and who had a LIFE there.
I got to watch him being discharged into the community TO SAVE THE GOVERNMENT MONEY and spend the next 30 years being constantly found 'sheltered' accommodation, making himself homeless because he could not help himself from hoarding and would therefore be evicted as a fire hazard, sectioned every year or so, two spells in prison, abusing his medication by either selling it or taking loads of it all at once because HE HAD THE RIGHT AS PART OF THE "CARE IN THE COMMUNITY" to refuse monthly injections and demand pills instead, and abusing any drug or alcohol he could get his hands on because it was preferable for him than having to endure the non-stop voices in his head. He was in constant ill-health, malnourished, filthy and utterly, totally neglected. He was simply unable to look after himself and completely unable to make the decisions that might have helped himself.
He eventually died after falling out of his window to get away from the council because he was about to be evicted again as a fire hazard AGAIN for the umpteenth time. And trust me, if he hadn't died that would still be being repeated again and again.
A whole life FUCKED and LOST because as someone with a lifelong mental illness he was not looked after because the state dismantled the one nd only system that kept him and so, so many others like him safe, just to make a short term financial gain.
And the whole country has been paying through the nose for it ever since.
