The key misconception here is that people want a single-income household and to have kids, and they've been Shanghaied out of this idyllic state of affairs by The Economy.

No. It's revealed preference, reflected worldwide. People think being single-income sucks. People think having kids sucks. They'll tell you they want to have kids and this and that if only it were "affordable", even when it's more affordable than it ever was for their parents. What their parent really had was a lack of contraception and other options; otherwise, they wouldn't've had kids and blamed it on something else the way you'd explain why you don't go to the gym more often. The way the world used to work has been a Ponzi scheme, and we've only now unlocked the ability to change the channel.

So no. There is no going back. And, even if there was, we'd only roll forward again since the fate of that lifestyle is to be defeated by your Bullshit Economy. It's a dead end. The only way is forward: growing posthumans in pods. We're only like 100 or 200 years away from that, and we'll make it there easily under a widening demographic pyramid.
