They meant the question showed a viewpoint that seemed to center entirely around you (also a rather libertarian thing, honestly).

‘Someone who would never build something for you’ sounds a bit like you’re expecting a tit-for-tat, I-do-this-for-you-so-you-have-to-do-something-for-me in everything, and that’s just not how societies work.

I’m curious; are you using that phrase to refer to, say, rich assholes who just take and take, or Nazi assholes that would rather cut off their own hands than build something a black person might use? Or are you using it to refer to people like severely disabled folks, or say, low-functioning autistic people, who society supports but who don’t have much capacity to ‘return the favor’?

Or are you just referring to future generations, who will be around after you’re gone?
