> failing to put a value on human life in each relevant context is akin to saying there is no value to human life at all. This is the crux of the problem with metric-based examination of nearly everything except physics. It is not nearly akin to that. If anything, saying that you can have a metric that measures the value of human life is much more akin to saying there is no value to human life at all -- all of life is "haggling over the price" as it were. Saying that it cannot be measured is just making an epistemological declaration of lack of knowledge. Not of the general form of "well, we just have to find the right variable and plug them in to the right formula" but of the form of "this is not well-suited to being reduced to a metric, as any such reduction will mask aspects of its value that are obvious but not easily measured". To be clear on the dangers (as if the McKinsey-fication of "dump the pollution in pooristan" wasn't enough) the problem is that given an imperfect approximation to some theoretical perfect metric, we have absolutely no way of determining how imperfect it is. There's nothing to measure it against except other potential metrics. There's absolutely no concept of ground truth -- the universe will not correct you (as it will if you measure mass incorrectly when doing physics).
