American society shows some degree of hierarchy in caring for the young, particularly at the highest and lowest levels of society. In general, the highest levels of society have the most personalized child care while lower levels tend to have less personalized and perhaps lower quality child care.
At the highest levels of society, people have individualized care for their children much of the time. They have people like nannies or au pairs who provide care. They also send their children to expensive preschools.
At the lower levels of society, children who are not cared for by their parents generally go to day care establishments. There, they are typically cared for in large groups without the kind of personalized attention and high quality educational activities that are available to those on the high end.
