Since the end of the Second World War, U.S. society has been relatively stable
and satisfactory. Aside from a few civil rights issues, no major problems
have directly hurt any influential population segments. It makes quite a
contrast with the labor rights movement before the war, the populist reforms
before then, and so on.
McCarthyism, Vietnam War protests, mass murders and abortion clinic bombings
have proved necessary to maintain the required level of social unrest.
