An excellent assessment of Social Security from Bill Gross of Pimco. “Rob Arnott of Research Affiliates LLC, sub-advisor of PIMCO’s all asset strategy and a co-collaborator with Peter Bernstein on several articles about risk and future asset returns, has advanced what I consider to be the most realistic take on Social Security and Medicare trust funds. Pre-funding these systems, he argues, “is basically irrelevant.” And (in my own words) it matters little whether the system is pre-refunded with Treasury bonds or privately held stocks. The fact is that both of these financial assets represent a call on future production. If that production could possibly be saved, like squirrels ferreting away nuts for a long winter, then Treasury IOUs or corporate stocks might make some sense. But they can’t. Future healthcare for boomer seniors can only be provided by today’s teenagers, twenty-somethings, and even the yet to be born. We cannot store their energy today for some future rainy day. Nor can we save food, transportation, or entertainment for anything more than a few years forward. Each must be provided by the existing generation of workers for those who have retired and are presumably incapable of working. And, as Chart I points out, the ratio of retirees to workers - the dependency ratio - soars from 0.2 retirees for every worker to 0.35 over the next 20 years or so. There’s your problem, and neither privatization nor any goodly number of government bonds deposited in the Social Security trust fund can solve it.”

Sizing Up Social Security

Unfortunately, Bill doesn’t mention the role of productivity improvement in alleviating the demographic problem by delivering more goods and services per worker. But to get better productivity we need investment, and to get investment we need savings.
