America's young people may be educationally unprepared to fill the shoes of baby boomers soon to retire from the work force, the National Center for Public Policy and Higher Education said Wednesday. "We're on the cusp of the retirement of the best-educated generation or set of cohorts in the history of the world," said David Breneman, director of the master's program in public policy at the University of Virginia and a producer of the report. "We need to worry very deeply about the young people coming along to take those positions."
