The only reason why China labor still works is because oil is cheap. The moment the Middle East stops dumping oil, China no longer works economically because of transit costs. It's already losing its advantage in the labor department. And you're right: there's two sides to the humanitarian coin: on one side you have what is effectively slave labor ending, on the other needed workforce numbers are going to decline. I think living wage is the only path forward but for that to work, humanity collectively has to do something very dangerous: a governing body that can tax the producers and pay out the living wage on a global scale so there's no tax havens. I don't think it's possible and even if it were, it would lead to ruin.
