I agree this happens for the vast majority of goods today. But does anyone have an example of where end-to-end societal cost is included in an item's purchase price?
Nope, the financial costs of cigarettes related diseases is actually beared by healthcare systems.
And nothing accounts for pain and suffering, comorbidity and impact on families having to live with members being ill or unable to work or prematurely dead. This is not something money can alleviates.
In recent years, and in some countries, maybe so. At least, to some extent. But not fully, I think.
