True, it requires some such arrangements. They aren't irrelevant. Democracy cannot long survive widespread, even justified paranoia and deep-seated fear of others. A mindset that suggests that we might share more in common than our differences at first blush suggest. These have never been qualities that carried us far beyond family, tribe, community or nation.
History abounds in examples of misplaced trust.
Balancing good sense and some hard-headed sophistication with that necessary naivete regarding the generous intentions of others is no easy task, but it's one democracy ultimately depends on. But contemporary life is peculiarly bad at such relationship-building at any and all levels. Many of us don't even have the same family for a lifetime. Jobs are no longer even advertised as offering security. The long-standing role of unions in protecting job security is seen, like job tenure arrangements, as counterproductive, inefficient, and possibly un American.
