Now say the same about (say) Jeffrey Dahmer, Ted Bundy, Ted Kaczynski (the Unabomber), etc., etc.: What would have happened if their parents had decided to just chilax on the beach and not have kids? That's right: Their "accomplishments" would never have been "shared" with the rest of us, either.

Yes, it's much harder to invest time, health, money and effort to properly raise kids who do wonders rather than to abuse and to raise fuckups. What is the point you are trying to make, that it's not worth trying?

No, the point is that you shouldn't cast shade on people who don't have kids and call them selfish.

There are a lot of good reasons why individuals decide, or happen through circumstance to not have kids.

And not having kids isn't some intrinsic mark of shittiness that people must wear.
