A TRILLION HERE AND A TRILLION THERE… World’s Major Economies to Come up $400 Trillion Short on Retirement Savings.

“We’re really at an inflection point,” Michael Drexler, head of financial and infrastructure systems at the World Economic Forum, said in a phone interview. “Pension underfunding is the climate-change moment of social systems in the sense that there is still time to do something about it. But if you don’t, in 20 or 30 years down the line, society will say it’s a huge problem.”

A shortfall of about $400 trillion could be reached by 2050, the World Economic Forum said. The figure is derived from the amount of money government, employers and individuals would need to provide each person with a retirement income equal to 70 percent of his or her annual earnings before leaving the workforce.

The gap is partially driven by an aging world population. Life expectancy has risen on average by about a year every five years since the middle of the last century, and half of babies born in the U.S. and Canada in 2007 may live to 104, according to the report. In Japan, the figure is 107 years.

“In the long run, we are all dead” is starting to sound dated.
