Valuations of Unskilled Labor

So here's a question: how many climbs like this per year should a human have to make in order to make what YOU make clicking you little tippy-tappy mice and pads and pocket-protected whiney little smart phones every day? Could you even make that climb, once in your entire life? Probably not. Yet do you depend on the signals relayed from that tower for your cute little iPhone? Likely, every single moment of every single day.

So how many climbs per year should it take to justify the climber's existence and feed his kids? 1? 6? 12? 24? As many as you can push them to do just short of dying? Or do you subscribe to the "F them, they're expendable unskilled monkeys, theory?" Show of hands?
