All that said, the main issue with the health insurance metric is that it would end up being a forcing function for the continued coupling of work and healthcare, which is bad and toxic.
And then it's "negotiated" down to $15K.
And then, if you pay cash, are you going to pay a portion of what they would have "charged" the insurer? Or what they "negotiated" with the insurer?
Toss a coin!
What "is", right now, leads us to the suggestion of int32_64, which would actually be a good metric to keep track of.
You are right about what "ought" to be, but until and unless we can get there, maybe we can at least base our information on what "is" in the moment, not on what we would like to be the case?
My metric for "fully employed" would be has a job, has health insurance and has enough money in savings to fully cover their out of pocket max. Could not be a barer minimum of survival.
What's the point of being considered 'employed' if you can be wiped out with one trip to the ER?
