Here is a sample of her writing:
What if, for those who didn’t feel otherwise compelled to have more kids, they decided instead to opt for greater pleasure and autonomy, for other opportunities for personal advancement and self-fulfilment?
...To be sure, low fertility accompanies a weak economy without fail. But to blame the markets for what happens in our bedrooms misses a radical reshaping of our worldview. It’s not just the economy, it’s liberation. The pursuit of happiness has emerged as our new national ideology, trumping the age-old belief that parental duty is the very definition, of adulthood. Some think it’s the height of selfishness; I say it’s progress.
...Over the past century, adulthood has come to promise more than just duty, but pleasure...we envision a liberated existence, one of satisfaction and fulfilment, a life built upon intentionality and individualism rather than obligation and role-filling. This liberated adulthood exists at odds with parenting...Instead of making a choice to enlarge our families based on stereotypes or cultural pressure, we can instead make that most profound choice our most purely independent one. It might even feel like something people rarely associate with parenting: it might feel like freedom.
That is exactly the kind of outlook you'd expect to emerge from within an advanced liberalism. If the aim is to maximise your individual autonomy, then you're going to have a problem when it comes to family life. Family life makes demands on us. It requires stable commitments that restrict what we might choose to do at any particular time. Family life, in other words, impedes our autonomy.
So what do liberals do? They try to recast the family to make it fit in better with autonomy. They can do this in a variety of ways. A commitment to family life can be delayed. Divorce can be made easier. There might be calls for the having of children to be "fitted around" a woman's life rather than be a core aspect of it. Lauren Sandler's solution is to have the absolute minimum number of children.
(A more radical solution would be to have no children at all; and the most radical solution is to simply live alone.)
The important thing to recognise is that within the framework of liberalism it doesn't make sense to commit to large families.
A traditionalist movement would therefore have a very considerable demographic advantage. If we were able to maintain a more traditional culture of family life, we would almost certainly have a much higher fertility rate than the surrounding liberal culture.
(Of course, that would only be an advantage if we were able to educate our children along traditionalist lines rather than having them become the next generation of liberals.)
Lauren Sandler's views are more evidence of what a dead-end road liberalism is for the society which adopts it. If we can operate within a different framework we will have a strength that liberalism lacks.
