In my new book, The Age of Deleveraging: Investment Strategies for an Era of Slow Growth and Deflation, I discuss nine reasons for slow U.S. economic growth and real GDP gains of about 2% annually in the long run.

1. U.S. consumers will shift from a 25-year borrowing-and-spending binge to a saving spree. This will spread abroad as American consumers curtail the imports of the goods and services many foreign nations depend on for economic growth.

Washington Post business columnist Steven Pearlstein does not mince words: too many people just don't get it.

Moreover, yours truly is not one to alarm, and typically views 'sweeping and dramatic statements' with a journalist's skepticism and a scholar's critical review.

But when the best economists you talk to, and business executives, and others in financial and investment circles, start reaching the same conclusion, from decidedly different vantage points, the dramatic statement begins to take on more weight, becoming more compelling.

'The reality of the facts on the ground'

Further, as Pearlstein incisively points out, there are reasons why a considerable portion of the American people are not 'getting it' regarding how serious the current situation is. Politicians are more concerned about ideology, partisan posturing, and teaching people a lesson -- if you can believe that they could be so irresponsible (my astonishment added, not Pearlstein's). Financiers have been very slow to admit to greed, arrogance, and incompetence. And foreign government leaders still view the financial crisis as 'an American problem.'

But none of the above changes what Pearlstein, and what my closest economist colleagues (David H. Wang, Richard Felson, Peter Dawson, M. Chandler, and Glen Langan) all argue is "the reality of the facts on the ground," to borrow a phrase from Israel's former Prime Minister and Defense Minister Ariel Sharon. Namely, that a massive, global deleveraging is taking place, and that absent a systemic rescue/intervention by the U.S. Government, in conjunction with interventions by other governments around the world, the world risks the bursting of a credit bubble that threatens to bring down the global financial system.

A flight to the dollar? Amid the United States' worst financial crisis in more than 20 years, perhaps since The Great Depression of the 1930s? It seems almost paradoxical, but that's the reality. So far. Stay tuned, an economist says.

The dollar has lost ground versus the world's other major currencies, amid this latest round of write-offs, bankruptcies and mortgage-asset-related stress on Wall Street, but the greenback has not plunged. In fact, the dollar is off its lows registered early Monday.

In early Tuesday trading, the dollar rose about a half-cent versus the euro to $1.4198, 1.5 cents versus the British pound to $1.7854, and a half-cent versus the Swiss franc to $1.1101. However, the dollar fell about 1 yen to 103.68 versus Japan's yen.

Themes: flight to quality, de-leveraging

Economist David H. Wang told BloggingStocks Tuesday the dollar's recent track displays two tendencies: a flight to quality and an unwinding of the carry trade -- i.e. a global de-leveraging.

"Although the U.S. Government and taxpayers are likely to spend more to deal with this financial crisis, and that implies more dollars in supply and inflation, institutional investors fear a decline or collapse in stock markets around the world, and are piling into the dollar," Wang said. "That is offsetting the dollar-weakening-effect of more U.S. Government spending. Essentially, it is flight to quality, so far."
