Yup. And in healthcare most of the focus is on Pharma (which is certainly profitable and gouging Americans but is a small piece of the pie) and insurance companies (which don’t even make much profits), but not on hospitals which constitute around 70% of healthcare costs.
“which don’t even make much profits”
You don’t have to make profit to waste a lot of money.
I think the answer to both tends to be "administration costs"
