THE quintessential dwarf
I can try to address the rest of you post later, but some of the work you mentioned (assigning value to each category of health services) has been done. The Urban Institute put out a report this month, actually. I pasted a couple of figures below. Of note, things that people claim are "unnecessary" and driving up premiums probably represent smaller sum of the pie than you think (see maternity care).
Replace the Child tax credit with a child tax and have maternity coverage covered by the state. State covered preventative care.
What is most inpatient services, cancers and stuff? Make that covered by the state. Everything else, you're on your own. You wanna buy specialty drugs that got $8k a month, knock yourself out.
Healthcare. Solved.
