1st of all-- women in extreme poverty, like, on welfare, don't have choices. because of our draconian welfare "reform" policies welfare moms pretty much (with minor, but notable exceptions) have to work-- or face losing their benefits.

2nd-- you have to have at least one wage earner making a pretty penny to be able to pull of supporting a family well.

i agree that it's about cultural values-- but until we make major changes in how we value mothering, women's work, and work in general (the fact that usually one income can't support a family)-- women are still going to be making these f*cked up choices every day. and it's not just about breastfeeding.
