A life is a life. If one life costs 7500 to save and another costs 15000 they are both still lives if you ask me. Should you spend 15000 to save one life or 7500*2 to save 2? If the one that costs 15000 is your child? Thats complicated of course. But the numbers arent really. Again, 7500 or more. As long as you have resources to share you can choose which life to save (or if you want to spend it on a computer and time on HN and let them all perish).
