According to information in the Medicare Trustees' latest annual report, Medicare's long-term fiscal gap now exceeds $60 trillion, or nearly six times the amount that the entire U.S. economy produces in a year. Yet politicians in both parties keep making the problem worse, most recently by enacting a $16.6 trillion prescription-drug benefit with no funding. How will these efforts turn out? How can we try to make Medicare sustainable? What should the program really be accomplishing? In Who Should Pay for Medicare? (University of Chicago Press, April 2004), AEI scholar and New York University professor Daniel Shaviro explores these issues. Shaviro, a leading legal and tax policy expert, addresses this book to seniors who feel entitled to expanded coverage, younger people who wonder what to expect from the government when they retire, and Washington policymakers who need a guide book to Medicare's future.
