Ok, hear me out for a minute.
What if I wanted to pool with several people, so that if any of us had unexpected medical needs, it wouldn't bankrupt any of us. Knowing that most of us would not need it.
And then, since we're all on the hook for each other's general health, we also agreed to share the cost of preventative care, because it was literally cheaper for us to all pay for preventative care than to try to just solo it and then hit the group with the cost of terminal cancer care instead of catching it early and doing a small excision. (and other such examples.)
And then what if we made the pool HUGE, to even further spread out the costs?
Sure wish there was a system that just did that, without trying to also generate insane profits off it.
