“If you survey Americans about how many children they want, on average they say about 2.5. That includes the ones like me who want six and the ones who want zero. But while people want 2.5 kids on average, in practice they have fewer — about 1.72 in 2018, the book says. Increasing America’s population needn’t involve regression from modern liberal ideas. It would just require making it possible for people to get the thing that they already want.
The book’s proposed policy changes are mostly changes at the margins — more immigration but not open borders, an expansion of public education to also provide free preschool and day care, subsidies and tax credits for parents, fixes to our housing and transportation policy so the cost of living isn’t intolerable.
Despite its simplicity — maybe because of its simplicity — it’s compelling. Matt Yglesias thinks America is good and it’d be good if everyone who’d benefit the country was allowed to live hereand everyone who lived herewas able to have their ideal family size. And while that simple vision elides a lot of challenges — some of which are beyond its scope — its vision of America is at least worth rooting for.”
