Of iPhones and Hindu villagers
And enjoy it you should. If you’re not a thief or a politician you earned it, which, being clear about it, is just a handy way of saying that you did stuff that Other People voluntarily value enough that Apple is willing to exchange an iPhone for your stuff (confident that it can then exchange it with Other People for what it itself really wants). The iPhone is yours and yours alone to enjoy. You earned it. You owe nothing to anyone — not, particularly, guilt.
What is more, both you and Apple, by freely exchanging only for how much each could get from each other, are subtly but importantly cementing the worldwide enterprise that has made it possible for the output of 4 Hindu villagers to seem tiny by comparison.
