Two articles I read today reminded me of earlier discussions here. Frist is John Mauldin's weekly newsletter, which this week is on "super trends" which includes demographic trends. It is at http://www.frontlinethoughts.com/art...p?id=mwo013004
I don't always agree with his newsletters but they are always thought provoking. This one referenced another article on aging at http://www.csis.org/gai/aging_index.pdf
which shows the US as one of the places with lower risk of economic problems due to the aging population. France, Italy, and Spain are flagged as the countries most at risk. An interesting study; some of the concern for year 2040 discussed on this board are much worse abroad.
