One of the core anti-capitalist aspects of hospitals are the guaranteed monopolies that many states grant hospitals, in the form of certificates of need. Searching for that term in the article resulted in 0 hits. Not sure how you can discuss this phenomenon without at least mentioning the guaranteed monopoly aspect.

CONs are what are really backing the loans that would otherwise be very unlikely to be available and are what made hospital acquisitions of the type discussed "profitable".

I was involved as representing a large vendor and investor in the hospital that was stiffed by a smaller version of one of these hospital pillagings and got a terrifying inside look at how these deals go down.

I've read there are positive effects of CONs and realize my experience was very limited.
