Oh interesting, I'd be happy to be wrong on that. :)
I figured they'd factor the staffing costs into what they charge the insurance, so it'd be more profit due to a higher fixed costs, longer treatment and some fixed percentage profit margin.
The estate costs thing is unfortunately an avenue I hadn't considered. :/
I still think it would be better if we removed the profit incentive entirely, but I'm pleased if the two interests are aligned if we have to have both.
