WASHINGTON - Bolstering the performance of the U.S. health care system is one of the biggest challenges facing the country, Federal Reserve Chairman Ben Bernanke said Monday.
New medical technologies and treatments are allowing people to live healthier, longer and more productive lives. However, the aging of millions of baby boomers coupled with rapidly rising heath care costs are accounting for an ever-growing share of both personal and government budgets — strains that will become increasingly burdensome unless changes are made, the Fed chief said.
