This is an interesting post. Over the last couple of days I've started to believe that "Generation X" has an ingrained sense of dissatisfaction built into us. Not because we are malcontents by nature, but because we are in the "unfortunate" position of having grown up after the doldrums of the 1970s. Our "problem" is that we came of age during the most optimistic periods in the last 50 years -- and we are not likely to experience that again anytime soon.
I think much of Gen-X's collective "problem" is the same as the baby boomers' problem, and that's having lived through nothing but prosperous times. I was reminded of that again this past weekend, due to the 60th anniversary of the D-Day invasion. The Great Depression was largely responsible for shaping the character of the greatest generation.
There are exceptions, of course. Not all Gen-Xers are spoiled, whining brats.
You should read The Fourth Turning. It explains ALOT about "our" generation--all of them in fact.
