Perhaps you should pay the peddler a bit more heed. I'm a firm believer that the next few years will smack of despair for investors. Folks a lot smarter than us are predicting a 50% haircut for the markets. During the great depression debt to GDP was 3x, today it stands at more than 14x. Continued devaluation of our dollar, failure of the European banking system, the continued deflating of real estate prices and staggering government and consumer debt, namely in the form of upside mortgages and HELOC's paint an ugly picture.
Some folks a lot smarter than us didn't see the financial crisis coming. Some did. Not sure where you're getting your debt / GDP figures but the fact is 'experts' are notoriously bad at making macro predictions because of the complex web of interrelated causes and effects. You can be a firm believer of whatever you like and I respect your decision to stay completely out of the markets but I wouldn't follow the advice of the creator of this thread because it wasn't very enlightening.
