Exactly -- the cited study simply observes trends but can't in any way make the claim that breastfeeding CAUSES lower earnings. No doubt women whose earnings decreased made, or were forced to make a series of choices that resulting in lower income and more time to breastfeed.
I have actually been one, and perhaps the rare, breastfeeding mother who has really appreciated Hanna's efforts to debunk some of the breastfeeding groupthink. I loved breastfeeding and can believe it has some health benefits, but I hated the sanctimony of La Leche league-types, and the idea that the decision whether to breastfeed was some kind of ultimately litmus test of motherhood. I appreciated Hanna's pointing out that some of the evidence about the long term health benefits of breastfeeding is shaky, largely because it doesn't "control" for charactistics such as parental health, income, race and education, things which could independently affect children in the long run.
So, Hanna, it's disappointing indeed to see you promoting research that is no more convincing than the studies you debunk!
