We imagine a group of tired, bored bureaucrats using actuarial tables for our age and illness to decide we probably won't live. Given that decision, they stop spending money on us beyond routine hospice care. That imagining is likely quite accurate.
On the other hand, everybody dies. And we know that a relatively large proportion of our total lifetime medical expenses will be incurred in our final months of life. Think how much could be saved if heroic measures were not taken in everyone's final months.
Perhaps we could lower the society's total medical expenditures by a third - that is an enormous saving. The model is triage.
