Is this really how you think it works? Do you honestly watch Game of Thrones because it helps to better other people’s lives? I’d be surprised. More likely, you start with “I like Game of Thrones” and end up with “it helps me to save the world.” I can’t read your mind. But that’d be my guess.
The problem is, you can justify too many things with this excuse. You already justified your iPhone when you could have bought a cheap android phone that has pretty much the same features. Paying the Apple tax is perhaps not the most effective way to save the world.
P.S. Is there any research done that suggests smartphones make people more productive?
The intent was to show that asking whether I don’t have anything more valuable to do than voting was an unfair question because even those who profess utilitarianism don’t always do the things that are most valuable in utilitarian terms. But it seems this strategy won’t work with you.
