Though it is increasingly for-profit, there are still large non-profit medical centers and systems. The for-profit are often larger, so are buying up the non-profits over time.I dont know anything about electeic shock therapy or neuralizers. But i disagree with the definition of business. USA healthcarw is busoness because it is "for profit." A very important distinction.
I've also looked into mental healthcare in the UK and think in some ways they are ahead of us and in others very far behind. Not an expert though
