Agreed. This is one of the areas of business where the MBA graduates of this century can and should really focus on: restructuring the modern corporation to allow for proper incentives and encourage innovation. Companies these days are more internally communist, with top-down centralized command. See http://www.salaminder.com/2010/02/large-corporations-inheren...
Yea.. there will always be overly optimistic bulls and overly pessimistic bears. The future always falls somewhere in between. If you look back a few years, you'll see that Amazon had its fair share of doubters. Analysts and critics questioned their investments, and wondered whether or not they would ever be able to sustainably turn a profit. Amazon's definitely done well, and their long term philosophy works. See http://www.salaminder.com/2010/01/amazon-diversification-diw...
Nevertheless, the OP definitely falls into the "overly enthusiastic bulls" category. What large companies have grown at 15% a year for 20 years?
