Why are we bottling mother's milk?

Great article in the New Yorker that I heard discussed on NPR. Here's the final paragraph:

Pumps can be handy; they’re also a handy way to avoid privately agonizing and publicly unpalatable questions: is it the mother, or her milk, that matters more to the baby? Gadgets are one of the few ways to “promote breast-feeding” while avoiding harder—and divisive and more stubborn—social and economic issues. Is milk medicine? Is suckling love? Taxonomical questions are tricky. Meanwhile, mamma ex machina. Medela’s newest models offer breakthrough “2-Phase Expression” technology: phase one “simulates the baby’s initial rapid suckling to initiate faster milk flow”; phase two “simulates the baby’s slower, deeper suckling for maximum milk flow in less time.” These newest machines, the company promises, “work less like a pump and more like a baby.” More like a baby? Holy cow. We are become our own wet nurses.
