This uncannily describes some of the culture in the Bay Area too. Areas of wealth probably create such environments. For example, mother groups start spiraling cycles of outrageousness in their birthday parties for their infants and toddlers, either trying to impress or avoid boredom --- I haven't figured out which. It would probably help if we had more cultural support for stay-at-home parents, where they could focus their energy on community support, and not just the children.
