Jacobin has a reputation of being in the category of affirm-your-biases news media, albeit one that is left-leaning. Something strong enough that you'd have a prior that any Jacobin article is going to blame all of society's ills on capitalism, and since it's strongly baked into the priors of its readers, there's going to be no real investigation after blaming capitalism.

Which this article basically does, at first glance. It assumes capitalism is bad for baby-rearing, doesn't really motivate why, and instead just goes East Germany had a higher birth rate than West Germany before reunification, then after reunification, it flipped, therefore capitalism causes low birth rates.
