So pound for pound what're the most effective life-saving measures we have at our disposal?
How do you decide
a priori what will be the "most effective"? How do you know whether that premature baby will become a heart surgeon or a mass murderer? When a man is drowning, do you check him for priors before jumping in after him?
As far as I'm concerned, the "most effective" life-saving measures are the universal ones that try to preserve ALL of the potential - for example, universal healthcare.
