Are there any occupations you uniquely oppose the existence of?
I did retirement home training and used to think it was a sweet job. Then I got in the business and underestimated how demoralizing it was as they give you the easy elders in training while the others make you, or at least me, really think of the fact the job just amounts to an unkarmic freebie.
Currently work in biotech, and have worked in medtech; I have had to integrate systems with insurers (payors is the industry term). I know exactly how fucked it is on a statistical level.
I used to work for an insurer. Our entire health system is just a steaming pile of crap. Providers will double or triple bill. Hospitals raise their rates through the absolute roof so they have room for negotiations. The uninsured people more often than not get billed at the unnegotiated rate which is many times what it should be. If the insurers are short on money or profit margins are down and their stockholders are angry they end up turning down shitloads of procedures looking at the statistics for what's least likely to cause lawsuits and death. Medicare requires you to go and recertify every patient every year, Mr Johnson's an amputee, well you better get him back in to make sure he still is or you're not going to pay for DME. Half the big insurers are still running on Big iron of one form or another, FTP over SSL coming hot off of mainframe.
