You know... that actually seems like potentially a good idea. Not just a tongue in cheek style good idea, but I'm thinking that this could be an actually for real good idea, and not just as a way to make "those other people" see what they're doing. I'd want this implemented as a way to make it easier for me to keep such things in mind!

(The "infected wounds" link is broken, though, so mind explaining the concept re that?)

The only real difficulty that I see is that as things change (tech, economic conditions, etc), the actual cost of saving a child and the relative costs of saving a child vs saving puppies, etc might shift around. So you'd need some way to dynamically rename chunks of the currency. For instance, if improving tech and such leads to the equivalent of 400$ being sufficient to save a child, then what was called a DC would have to be renamed 2 DC.

This would be confusing.
