I really enjoyed this Planet Money episode on the economic costs of making breast pumps free. Although I'm not sure what I believe about the costs to society and whether it's worth it, I can tell you that I'm very grateful that I can get a free pump for this child! And I will most definitely be getting the best one I can.
