> we, as a society, cannot afford to pay
...because the giga-rich stole from us. Let's not couch their actions in the passive voice, or pretend this situation just happened somehow. The "neoliberal" (ie not new or liberal) takeover of America was orchestrated by the rich for their own benefit, and almost 40 years later we're still suffering the effects: stagnant wages, rising profits, and ever-increasing wealth inequality.
There is indisputably enough of wealth for everyone on Earth to die with dignity. The problem is distribution, not quantity.
> several hundred thousand to multiple millions of dollars in healthcare costs
Healthcare price, not cost. The underlying cost is quite affordable.
The price is not because the insurancestudent debt/pharmaceutical/healthcare industries extort obscene profits (and taxpayer subsidies!) by leaching off a life critical, non-negotiable service. See above.
