@maporsche,
The reality is the claims submission and adjusting jobs are continuing to diminish as a result of automation. I see it literally every week. A group of friends/former colleagues was laid off yesterday. Data entry jobs are pretty much gone - there are only a few groups of contract positions that come up when companies merge and their systems need to be lined up. Adjusting positions have been disappearing since the late 1990's. Examiner roles are increasing (but not at an equivalent rate) to deal with disputes/mediations etc.
Management jobs will decrease as systems are merged but that's been happening for over two decades already.
Trying to argue against single payer on a jobs basis just isn't a winner.
There will always people needed to work in the system as people will continue to submit claims but automation has changed this significantly already - and will continue to change it at least as much as bringing in single-payer could.
the first insurance head office I ever saw looked remarkably like this
then we went to punch cards and giant reels and office jobs started to leave the industry - my dad's first insurance job included being on-call 24-7 to go in to switch the reels out
I remember when computer rooms were dedicated buildings with double airlock doors
now we work in bookable sushi bar spaces like this
each one of the chairs in the second photo represents the capacity to do more work than the whole room in the pic from the 1950's
times changed and are changing

I have a somewhat unique perspective as my dad worked for a life and health carrier starting in the year universal health care started in Canada, and I've worked in and around the industry for 35 years. As it's something we have in common, we talk about changes in the industry and jobs a fair bit.
