“The Aftermath: the Last Days of the Baby Boom and the Future of Power in America” by Philip Bump (Viking) At the outset of his book, columnist Philip Bump makes it clear that he's writing about an America undergoing massive shifts as the baby boom generation ages. “We are living through a historic disruption of the American empire," The Washington Post national columnist writes in the introduction to “The Aftermath: the Last Days of the Baby Boom and the Future of Power in America." What that disruption means for the country remains uncertain in many areas, but Bump leaves no stone unturned as he takes a detailed look at the rise of the baby boom generation, its impact on the United States and the implications of its final days.
