My grandfather was never rich. He did have some money in the 1920s, but he lost most of it at the tail end of the decade. Some of it disappeared in the stock market crash in October of 1929. The rest of his deposits fell victim to the collapse of New York’s Bank of the United States in December of 1931.

I wish I could say that my grandfather recovered from the wrath of the stock market disaster and subsequent bank failures. For the most part, however, living above the poverty line was about the best that he could do financially, as he buckled down to raise two children in Queens.

There was one financial feature of my grandfather’s life that provided him with greater self-worth. Specifically, he refused to take on significant debt because he remained skeptical of credit. And with good reason. The siren’s song of “you-can-pay-me-Tuesday-for-a-hamburger-today” only created an illusion of wealth in the Roaring Twenties; in fact, unchecked access to favorable borrowing terms as well as speculative excess in the use of debt contributed mightily to the country’s eventual descent into the Great Depression. G-Pops wanted no part of the next debt-fueled crisis.

Here’s something few people know about the past: Consumer debt more than doubled during the ten year-period of the Roaring 1920s (1/1/1920-12/31/1929). And while you may often hear the debt apologist explain how the only thing that matters about debt is the ability to service it, the reckless dismissal ignores the reality of virtually all financial catastrophes.

During the Asian Currency Crisis and the bailout of Long-Term Capital Management (1997-1998), fast-growing emerging economies (e.g., South Korea, Malaysia, Thailand, etc.) experienced extraordinary capital inflows. Most of the inflows? Speculative borrowed dollars. When those economies showed signs of strain, “hot money” quickly shifted to outflows, depreciating local currencies and leaving over-leveraged hedge funds on the wrong side of currency trades. The Fed-orchestrated bailout of Long-Term Capital coupled with rate cutting activity prevented the 19% S&P 500 declines and 35% Nasdaq depreciation from charting a full-fledged stock bear.

Did we see similar debt-fueled excess leading into the 2000-2002 S&P 500 bear (50%-plus)? Absolutely. How long could margin debt extremes prosper in the so-called New-Economy? How many dot-com day-traders would find themselves destitute toward the end of the tech bubble?
