"As networked individuals, we have the freedom to design the community we want to live in. And if what we choose isn’t working for us, we can always try something else."
this a really disrespectful attitude to the kinds of decisions made by their parents to enable them to live such a lifestyle, I'm not saying they owe people to have children just respect that abandoning something when it doesn't suit you is not how great adults are raised, but rather children growing up secure in the knowledge that they are so loved that their parents gave up such a lifestyle to ensure that even when things aren't going well they will be loved and cared for.
We all contribute to society in our own way and it would be great if we could all be proud of what we've contributed without having to compare to others. If you're raising children cherish them, if you're single cherish that, neither decision takes anything away from the other.
