"Child care has grown up under different circumstances than education and probably for a mixture of reasons, good and bad. There are many systems of child care, some private, some public. As compared with primary and secondary education, there is clearly less need for coordination. The sequencing of classes is much less important. It would appear that the ability of parents to monitor the conduct of the child care activity is much greater because the activity is much closer to everyday experience and knowledge. Most of the informational and structural arguments for the public supply of education are absent in the case of child care. Reputation and experience may suffice for adequate monitoring."
