Essentially, the going theory seems to be that society would be better of if it would delegate childcare to less people per child, contrary to the "traditional" one on one of mothers and their children. (Thinking about it, in the old days mothers had more children, so it was rarely one on one either).
Also, it seems to consider having children merely as a productive factor for society, rather than something people do for its own sake.
I like to compare children to Ferraris, as both are expensive (children probably even more so than Ferraris).
So in analogy, people like to buy Ferraris, but society would be better off if those Ferraris would be parked in somebody else's garage. Think about all the time people waste driving their Ferraris, which they could have otherwise put to productive use for the benefit of society.
Given that, what’s a simple thing that we could do to make life better? Make it easier for people to cope with that. Good, easy childcare is one clear way to do it.
It’s also wrong to suggest this is a rich people problem. If anything the lack of childcare is an even more acute strain at the lower end of the wage scale.
Completely free childcare for everyone may be unworkable or undesirable for a variety of reasons, but it seems clear we can do a whole lot more, and we would benefit in the aggregate. Not the least of which because more people from different backgrounds in the workplace is a great way to build empathy and creativity.
