I didn't say everyone was worth equal amounts. This vote is about the cheapest Human lives to save, which would start to cost more as we save the cheaper lives.
As I see it, a person is worth as much as how much they can help the world, including artistic or other hard to measure things, depending on which things people value about their skills. Those people you listed may be worth a lot. I'm not saying their lives are worth what this median-vote says.
You're not asking the value of a human life, then, but the cost.
You know what's great at balancing benefits and costs?
The Market.
