This is definitely worth a read. Written from a completely different view point from my own, she comes up with what I believe to be one of the most heart-wrenching discussions of "birth dearth" I've read in a long time.
Here's an excerpt, but do yourself the favor and go read the whole thing.
To be almost ridiculously sweeping: baby boomers and their offspring have shifted emphasis from the communal to the individual, from the future to the present, from virtue to personal satisfaction. Increasingly secular, we pledge allegiance to lower-case gods of our private devising. We are less concerned with leading a good life than the good life. We are less likely than our predecessors to ask ourselves whether we serve a greater social purpose; we are more likely to ask if we are happy. We shun values such as self-sacrifice and duty as the pitfalls of suckers. We give little thought to the perpetuation of lineage, culture or nation; we take our heritage for granted. We are ahistorical. We measure the value of our lives within the brackets of our own births and deaths, and don't especially care what happens once we're dead. As we age - oh, so reluctantly! - we are apt to look back on our pasts and ask not 'Did I serve family, God and country?' but 'Did I ever get to Cuba, or run a marathon? Did I take up landscape painting? Was I fat?' We will assess the success of our lives in accordance not with whether they were righteous, but with whether they were interesting and fun.
If that package sounds like one big moral step backwards, the Be Here Now mentality that has converted from 60s catchphrase to entrenched gestalt has its upside. There has to be some value to living for today, since at any given time today is all you've got. We justly cherish characters capable of fully inhabiting "the moment", of living, as a drummer might say, "in the pocket". We admire go-getters determined to pack their lives with as much various experience as time and money provide, who never stop learning, engaging, and savouring what every day offers - in contrast to dour killjoys who are resentful and begrudging as they bitterly do their duty. For the role of humble server, helpmate and facilitator no longer to constitute the sole model of womanhood surely represents progress for which I am personally grateful. Furthermore, prosperity may naturally lead any well-off citizenry to the final frontier: the self, whose borders are as narrow or infinite as we make them.
Yet the biggest social casualty of Be Here Now is children, who have converted from obligation to option, like heated seats in the car. In deciding what in times past was never a choice, we don't consider the importance of raising another generation of our own people, however we might choose to define them. The question is whether kids will make us happy.
