Last Book Club on the Left discussion

So I'm looking for stuff for my real life book club and came across this question on LitLovers and thought it was interesting:

McNamara writes about an incident in her own neighborhood in Los Angeles, when her neighbor’s house was robbed. "We make well-intentioned promises of protection we can’t always keep. I’ll look out for you." Do you think we, as a society, have lost a sense of neighborliness? What factors do you attribute to this loss? How have changes in technology, economics, architecture—house and planned community designs—impacted you, your neighborhood, and society? Is there a remedy to bring us closer together?
