During the late 1990s when the dot-com fad had become a full-fledged frenzy, it seemed as though the entire population of the Western world was rich. If your net worth didn't have two commas in it, then, well, there must have been something wrong with you, no? What was wrong, actually, was that the majority of these nouveaux riche were riche only on paper. They may have been worth millions, but those millions existed as stocks or stock options.
