The Talmud lists the prophetic signs that will point to the coming of the Messiah:
          an increase in oppression,
          rampant inflation,
          pride,
          irresponsible government,
          wars,
          widespread poverty,
          despising of wisdom,
          lack of respect for elders
          and righteous men,
          and the breakup of families.

Other problems as final signs:
          famines,
          epidemics and plagues,
          blasphemies,
          international warfare,
          unspeakable suffering,
          hatred and betrayal,
          evil governments,
          hatred of religion,

These are called 'birthpangs' of the Messiah.
