David's Time With Peter F. Drucker 2020.3.24 An aging population——the demographic phenomenon that now preoccupies economists, politicians and the public in all developed countries——is nothing new. Life expectancies have been growing in the developed world since the 18th and certainly since the 19th century. They have not even been growing very much faster the last fifty years than they did in the last hundred and fifty years. And we also know how to deal with the problem. It will be difficult, painful, turbulent and terribly unpopular, to be sure. But wthin the next twenty to thirty years the retirement age in all developed countries will have to move up to around seventy-nine or so——seventy-nine being the age that, in terms of both life and health expectancies, corresponds to age sixty-five in 1936, when the United States, the last Western country to do so, adopted a national retirement plan (Social Security). ——《Management Challenges for the 21st Century · Chapter2》(Peter F.Drucker,1999)
