Wealth Reversion Has Arrived

Thoughts from the Frontline
Dr. Woody Brock, president of Strategic Economic Decisions, Inc.: "We have written about "mean reversion in national wealth growth" for the past five years, and explained why it would soon have to occur. In this regard, one of the most fundamental of all theorems in economics tells us that national wealth must (and empirically does) grow over the long run at the rate of GDP growth.

Well, wealth reversion has now arrived, and will be with us for far longer than most anyone expects. First, wealth has already contracted by $500 billion in 2007. Second, wealth contraction will continue to occur until mid-2009 when house prices reach their trough. And third, wealth growth will probably be sluggish up to and beyond 2020, running at about 3%. One reason why is that most baby boomers have their money in their houses--not in traditional defined benefit pension plans. Accordingly, the only way they will be able to retire in the style they expect is to sell their houses to one another. Next joke.

How remarkably this new 2.5% wealth growth regime of 2007-2020 will differ from the previous regime of 1981-2006! During that period, US net worth soared from $10 trillion to $57 trillion--an arithmetic average growth rate of 18% and a compound annual growth rate of 7.2%. For readers who doubt what we are arguing, note that the average growth of wealth across the two regimes being analyzed compounds at exactly 5.5%. This is precisely the long-run growth of nominal GDP. And all the Golden Rule Theorems in Growth Theory require that wealth growth and GDP growth converge to the same growth rate in the long-run.

This will fundamentally change both American politics and daily life. In particular, it will be the final nail in the coffin of hopes of early retirement for most baby-boomers. In short, "wealth reversion" is finally coming home to roost. What cannot go on does not go on." (4/14/07)
