I was the second to vote to close, so I'll voice my rationale.
The question, as phrased, seemed - and still seems, so some extent - to me to be more a reflection on our world, not a built world. The title itself, "How can . . ." (emphasis mine) is also along the lines of, "This is a commentary on our world." At least, that's how it seemed to me.
For what it's worth, I voted to close not as off-topic but as unclear - which sucks, because the close message indicates that I thought it was off-topic. I thought it was on-topic, I just didn't understand it, because it seemed like the heart of it wasn't as prominently placed.
As for my rationale for voting to reopen. . .
Is world-building reserved for subject matter suitable to an adult audience?
(Cough cough) Awkward moment. Funny, how I'm a kid voicing my opinion here.
There wasn't really much wrong with the question, looking back. Bret called it "rambling", and tried to fix that a bit. It just seemed a bit confusing. But I think it's all right because it discusses a societal aspect. We've had . . . erm . . . controversial questions regarding in-world beliefs, and they're on-topic. The beliefs discussed here are simply different. And they aren't beliefs, come to think of it.
I for one look forward to seeing your answer, should the question be reopened.
