A few thoughts:
1. According to sociologists and other scholars who have studied American suburbs over the last century, an overriding concern in suburbs is to protect families and let children flourish. The assumption is that suburban life – with its lower density, single-family homes, more space, better schools, lower crime – will benefit children in the long run.
2. At the same time, suburbs are also based on exclusion. For decades, only white people – and certain ones at that – were allowed in many suburbs. While this is officially off-limits today, it can be accomplished in other ways such as through exclusionary zoning, drawing school district boundaries, and through police.
3. Police can and have reinforced the race and class based exclusion in suburbs. This could range from sundown towns to watching fire bombings in Cicero, Illinois to harassing motorists, residents, and protestors in Ferguson, Missouri. Wealthier suburban residents generally do not want to involve the police in their conflicts but they can and do at times.
4. Many suburbs offer limited social services. The expectation is that residents will have the resources to provide for themselves or that corporations and local charities will provide.
5. Many suburbs like having their own police department. This allows them to retain local control, important for #2 and #3 above.
6. For an academic study of how this works in wealthier suburbia, I recommend America’s Safest City: Delinquency and Modernity in Suburbia. From the book description:
Adolescents, parents, teachers, coaches and officials, he concludes, are able in this suburban setting to recognize teens’ need for ongoing sources of trust, empathy, and identity in a multitude of social settings, allowing them to become what Singer terms ‘relationally modern’ individuals better equipped to deal with the trials and tribulations of modern life
