In the US and other countries, public policy and discussion have categorized individuals into groups that can be differentiated from all others. We have seen this with regard to race and gender, youth, working parents, single mothers, and the aged. Each of these groups has either claimed or been seen as being deserving of some special treatment. Equal treatment, affirmative action, employment schemes, access to quality education, health care, day care, long-term care, and special residential options have all received attention from the government. One of the groups that seems to have disappeared from this panoply of policy concern is the healthy, educated, well-off seniors who are the subject of this book. It is true that the vast majority of them are not in need of the kind of attention and subsidy that the other categories of citizens are given. But they do have aspects of behavior, lifestyle, and income that are worthy of examination. They are in transition from a situation in which they are relatively independent from government intervention to the years in which they will be increasingly dependent upon outside assistance, not all of which will require subsidization from the government. As we argue in this book, much of that behavior can be of considerable benefit to the economy of a city.
