Facebook and Google have very real revenues and very strong growth. I have a hard time seeing how you can be correct that they somehow need Greater Fools to "propel" them. Consider: Those companies could produce a very strong return for their investors if the stock market never existed. Because they make loads of profits they could pay out to owners. Anyway -- Generally, our points are orthogonal. I am talking about the way things Should Be, based on my subjective opinions of what makes for sustainable business growth. I think this boom bust bubble pattern is Bad (capital b to signify squishy concept) for the tech sector. You, on the other hand, are talking about What Is. (Aside from the Google/Facebook misfire.) You have here a four year chart showing tech sector/stock market correlation. I do not dispute that. In fact, my whole point is that maybe not much has changed on the financial side tech industry in the last 10 years. For all the smart people in tech it is still as vulnerable to bubble meltdowns (the crater in your chart) as anyone else. I think that's too bad - tech should be above it.
