... For the "acceptable losses" argument I added pricing of a year of life based on MoT Value of Statistical Life, but flipped from "Amount willing to spend to save a life" to "Lives willing to lose to save money"- any countries below the orange line had economically "acceptable" loses vs NZ.

I would have expected the orange line to have more of a scope? Or am I misunderstanding?

Very nice. Where did you source the spending data?
