Well, isn't this lovely. There's a Star Chamber in Great Britain which exists to find elderly individuals incompetent (because of Alzheimers, dementia or mental illness), seize their assets, and presumably lock them away in a facility. I'd call it enslavement except people generally make slaves of those whom they might find of use. This is rather that sort of slavery where the benefit to the slaver is entirely of a moral cast: the beneficial glow of having done a good work, of having saved these old dears from the exploitations of their grasping, depraved parasite spawn, of having put them into a gentle, soothing trajectory towards the Great Recycling Box in the Turf.
All great evils are done by those who think highly of their moral certitudes.
