FTFY, it's remarkably expensive, low touch, and uninformed vs other countries. The US's medical and food programs focus exclusively on money rather than quality of care or informing parents. We simply give out prepaid 'credit' cards and medical cards, there is little to ensure that they are used correctly or in a healthy manner. We don't do much to ensure that kids actually see doctors, we don't do much to ensure quality of food choices, cooking, or health, the school lunch programs are littered with terrible nutrition and only covers lunch and sometimes breakfast.
The most telling thing about America is that we honest to goodness keep infant formula in grocery stores...in security cases.
