The Pew Center reports that Americans’ views of these conflicting economic arrangements haven’t changed much since 2010. That’s from an overall survey, however; some Americans’ views and political participation have surely changed.
Which matters more: that the views of most are unchanged, or that some are of changed opinions (and perhaps increased motivation)? I’m not sure.
