The U.S. retirement system, and the workers and retirees it was designed to help, face major challenges. Traditional pensions have become much less common, and individuals are increasingly responsible for planning and managing their own retirement savings accounts, such as 401(k) plans. Yet research shows that many households are ill-equipped for this task and have little or no retirement savings. Chapter 1 examines these challenges, drawing from prior work and others' research, as well as insights from a panel of retirement experts on how to better ensure a secure and adequate retirement, with dignity, for all. Chapter 2 examines key challenges U.S. participants face with: (1) unclaimed retirement accounts in the United States, and (2) complying with U.S. tax reporting requirements on their foreign retirement savings.
