Assuming you meant avoidable, I don't think there is ANY system of business that avoids EVERY avoidable death. Often saving each life may be 100% possible, but it may not be possible to save every life. As a real example, I would guess most civilians in Gaza that will die in the next month could have their death avoided if their singular life were the #1 priority of every around them. However, I do not think the humanitarian crisis in Gaza can be entirely solved within the next month so that no civilian will die (even assuming cooperation from both sides and massive external aid).
The absolutism in your comments is not conducive to productive conversation. I would guess there are many people on HN that are too pro capitalism and don't recognize how it fails many people, but being absolutist to the point of impossibilities does not make you convincing.
