‘The system’ is a pretty darned broad stroke. GAO appears to work ok in that regard. Although, tens of thousands were harmed getting to that point…so, ‘works’ is a pretty broad stroke, too.
Edit, Too: Um. I’m not sure what you think you found, but that bears no relation to the report I mentioned, which is talking 100’s of millions and direct failures in Public Health measures.
And no, I don’t need any instruction as to what an epidemiologist is or does, thanks. Well aware. Cannot understand why you are bent on pimping CDC’s failures and excesses, though? Just trolling, or personal interest of yours?
