I dont think that all flow through effects are (or even can be) quantified by this sort of analysis. It is surely much easier to measure the growth from an investment account than to quantify the impact of a human life or the downstream effects of improving a human life. As far as I am aware, efforts to quantify this sort of effect are not yet available to the level that I would feel very confident about a side by side comparison. If you are aware of something you believe allows for such comparison, I would be very interested in reading that.
