It wouldn't be the same metrics, which was my point - I wonder what metrics you'd be focusing on when determining the value of this expression of altruism. You couldn't directly compare against action that helps a very different populace in different ways, but you will need to indirectly compare and you'll want to directly compare against alternate more similar interventions (like buying used cars for the already-bankrupt or whatnot).

I guess I'm looking for a way to move from "nice alternative" to "effective alternative for X and Y goals".
