For instance, do you believe your life to be worth less than that of everyone else who has more money than you? What if that money was inherited and they didn't work a day in their lives? What about the life is say, Nikola Tesla who didn't have much money but laid foundations upon which a lot of our world is built today?
Is the person who negotiated for more money than you make now (while doing less useful work) have a more valuable life than yours?
Imagine you were walking with a friend of equal net worth, by your logic, if they suddenly found $100 on the ground and took it, their life is suddenly more valuable than yours? What if you both got struck with an illness and the doctor triaging said "huh, Kaiyou is worth $100 less than their friend so I guess I have to let him die and focus on the slightly wealthier person".
Have you ever enjoyed the company of someone who was economically worth less you? What of the benefits of their contributions (think of your teachers, researchers, janitors, construction workers, etc.). Assuming human value can be simply measured in made up constructs of money and debt obligations ignores a lot of what makes our experience richer
> Is it moral to replace broken things instead of trying to fix them, considering that fixing will be more expensive and the thing might just break down again after a while anyway? That's not a question about morality, is it? Except if you replace "things" with "humans". I personally do not understand why this difference exists, however.
It seems a big driver of your beliefs is that humans are worth nothing inherently. Morality enters the game entirely because we're conscious and have created morality questions and concerns for ourselves. Your shoes never quite evolved to have those questions (though if we ever achieve some loosely defined form of AGI, those questions will come into play)
