NEW YORK ( TheStreet) -- You know, what I love about Thanksgiving -- and this country -- is the mistakes.
Because have you ever had a perfectly cooked Thanksgiving meal? Of course not. That's the point. The miracle of this day is that the untender turkey and mushed mashed potatoes somehow swirl up into a marvelous, greater-than-the-sum-of-their-parts cassoulet.
This turkey-and-stuffing-induced glow makes for the perfect time to take an intellectual stroll through American errata, from the simply silly to our deepest missteps -- then serve up the investor lessons. After all, as Churchill said, "All men make mistakes, but only wise men learn from their mistakes."
The Leisure Screw-Up
The tip-top, first-tier American blunder is of course from the late 1970s. According to the Fashion Encyclopedia, one Jerry Rosengarten matched jackets and pants made of then-new polyester fabrics to create a single suit. This wonder garment would not be for work. Oh, no. This super suit was for leisure.
And the doomed "leisure suit" was born.Luckily, Rosengarten and the rest of us wised up to the coyote ugly of leisure suits, and they departed from our department stores. Smart marketers, such as Under Armour (UA), eventually worked out that synthetic fabrics work best when people sweat, not sit around. And $5.4 billion in market cap was created.
