The sharing economy and on-demand services are weaving their way into the lives of (some) Americans, raising difficult issues around jobs, regulation and the potential emergence of a new digital divide A number of new commercial online services have emerged in recent years, each promising to reshape some aspect of the way Americans go about their lives.
