Things that Americans do collectively that do not involve the government or their job:

-Credentialed professional associations from surgeon to bricklayer.

-Labor unions.

-High school, college, and professional sports fandom.

-Music fandom.

-Comicon style fandom.

-Furries.

-Sports and hobby participation.

-Chamber of commerce.

-Party politics.

-Civic organizations and charities.

-Religion.

-HOA and neighborhood associations.

-People associating based on their sexuality.

Most of the time that an adult citizen engages with a government employee it's a cop and that sucks, so that really isn't a collective interaction. In any case, there isn't a whole lot of collective mindset when you lay out what groups of people really care about.
