The problem's hard to define, isn't it? I'll field this one.
Anyone carrying out child abuse like this at home will get arrested. See what happened in Florida. Some douchebag locked his kid in his room, installed video surveillance all around the house, etc, etc.. welcome to jail, asshole.
It's simply about equal enforcement of the laws. Anything that a parent can't do at home, a private party shouldn't be able to do either. Withholding of food and water, child labor, constant emotional and physical abuse through a wide variety of insane demands and threats.. sorry guys, that's illegal. Welcome to jail. It's simply that somehow this has all become okay when the children are institutionalized.
The real goal is to make sure police, regulatory officials, and everyone else thoroughly understand that it's still not okay. This is the real goal. Once that is established, everything else follows.
Are they locking kids up and passing themselves off as a mental health facility? This shouldn't be legal, but if they claim to be a residential treatment facility, a "therapeutic boarding school", or anything else that even resembles either (these guys get slimy in this regard), they need to be licensed and regulated by the State. This means that the kids have the right to a psychiatric examination and a hearing before a judge; if they're not actually mentally ill, they can't be locked up like that, just as it is with a state facility. Regulation also means inspections, and also means independent interviews with the kids. "But they're manipulative and they lie.." Yeah, asshole, that's the regulator's job to determine, not yours.
Are the kids living in fear? Are all of them exhibiting the same sort of automatism that's common in cults? Are they malnourished or being given drugs such as SSRIs willy-nilly, without respect to whatever actual mental problems they may have? That's not okay. It's time to shut the place down.
And that's what will happen as the result of actually enforcing laws: mass shutdowns and arrests. What happens in these places is fundamentally wrong and child abuse is still illegal. It's just a matter of getting the cops to do their jobs.
Now, if there are still some places after THAT that are still around.. let 'em go. They're not the target.
