I dont know what the schools costs and expenses are, so I could not answer that. The schools charge about $150/day. A hospital non critical stay is $1,000 to 2,000 per day. So relatively speaking these schools are fairly inexpensive. Hazeldon (rehab) in Minnesota can cost upwards of $1,000 a day.
The school actually charges $170 a day with a $5,300.00 per month tuition. If you consider that inexpensive then I would question your understanding of basic financies. A year tuition at RC would come to $63,600.00 not including incidentals. Incidentally a year at Harvard would run you about half of that, and you'd benefit far more and not be abused.
I'd be interested in seeing some source citing your claim of of $1,000-$2,000 per day for a non critical stay at a hospital. Keep in mind even if that is true, factor how much a person is paying out of pocket expensive once their medical insurance kicks in.
Hazeldon is very expensive, however it's much more effective, much less abusive, isn't coerced, and doesn't last nearly as long and therefore doesn't cost as much as RC.
But I do agree that they need to figure out how to keep these kids safe and get some night staff in even if it means passing off the cost to the parents.
What if instead of passing it off to parents, Buchi took a slightly smaller cut? I can tell you first hand from the year I spent locked up in HLA, that very little is actually spent on the kids. The place is a dump and every corner that can be cut is.
