According to the Pew Research Center,

…about two-thirds of the public (66%) believes there are “very strong” or “strong” conflicts between the rich and the poor—an increase of 19 percentage points since 2009…

According to the new survey, three-in-ten Americans (30%) say there are “very strong conflicts” between poor people and rich people. That is double the proportion that offered a similar view in July 2009 and the largest share expressing this opinion since the question was first asked in 1987.

As a result, in the public’s evaluations of divisions within American society, conflicts between rich and poor now rank ahead of three other potential sources of group tension—between immigrants and the native born; between blacks and whites; and between young and old.

As John Fugelsang put it, “‘Class Warfare’ is when the bottom 98% fights back.”
