People always do things "because they want to" - even if forced to do it at gunpoint (they could choose to die, of course).

Things on many metrics are likely better now than any point in human history, but people's perceptions of that are way off.

But it doesn't change that there are people who would like to start a family and feel they can't. Obviously they can, as the mechanics of it all hasn't changed in the last million years, but they choose not to.
