Well-being and Social Policies
The economic effects of an ageing population are considerable. Older people have higher accumulated savings per head than younger people, but spend less on consumer goods. Depending on the age ranges at which the changes occur, an ageing population may thus result in lower interest rates and the economic benefits of lower inflation. Some economists (Japan) see advantages in such changes, notably the opportunity to progress automation and technological development without causing unemployment. They emphasize a shift from GDP to personal well-being.
However population ageing also increases some categories of expenditure, including some met from public finances. The largest area of expenditure in many countries is now health care, whose cost is likely to increase dramatically as populations age. This would present governments with hard choices between higher taxes, including a possible reweighing of tax from earnings to consumption, and a reduced government role in providing health care.
The second-largest expenditure of most governments is education and these expenses will tend to fall with an ageing population, especially as fewer young people would probably continue into tertiary education as they would be in demand as part of the work force.
Social security systems have also begun to experience problems. Earlier defined benefit pension systems are experiencing sustainability problems due to the increased longevity. The extension of the pension period was not paired with an extension of the active labour period or a rise in pension contributions, resulting in a decline of replacement ratios. In recent years, many countries have adopted policies to strengthen the financial sustainability of pension systems, although the challenges regarding pension adequacy remain.

Famous quotes containing the words well-being, social and/or policies:
“The ability to think straight, some knowledge of the past, some vision of the future, some skill to do useful service, some urge to fit that service into the well-being of the community,—these are the most vital things education must try to produce.”
—Virginia Crocheron Gildersleeve (1877–1965)
“It’s frightening how easy it is to commit murder in America. Just a drink too much. I can see myself doing it. In England, one feels all the social restraints holding one back. But here, anything can happen.”
—W.H. (Wystan Hugh)
“We urgently need a debate about the best ways of supporting families in modern America, without blinders that prevent us from seeing the full extent of dependence and interdependence in American life. As long as we pretend that only poor or abnormal families need outside assistance, we will shortchange poor families, overcompensate rich ones, and fail to come up with effective policies for helping families in the middle.”
—Stephanie Coontz (20th century)
