AEI has a piece on this; unfortunately, their piece proceeds from some false premises.

Developing a National Paid Parental Leave Policy

It’s interesting that folks of a bent proceed from such claims. They always decline to establish, for instance, that we need a national policy for parental leave. It’s such a widespread failure that I have to conclude it’s deliberately Alinsky-esque in its attempt to control the discussion.

The United States is one of two countries without a national policy providing new mothers with rights to paid leave following the birth of a child.

And then this non sequitur keeps getting dragged out as if it matters that we don’t look like the rest of the world. Never mind that, more substantively, we aren’t like the rest of the world, so there’s no reason we should look like the rest. There aren’t very many federated republics extant.

At present, we simply do not know what the ideal leave program for the US would look like.

Yes we do. It’s what each of the 50 States in our republic think one would look like–it’s what the citizens of each of those States think is best for themselves. Full stop.
