While I know the stock market drives the world economy, I also think it can be disastrous. With the stock market, profit isn't good enough, it must always be increasing profit. One can not simply make 1 billion a year, it must be 1.1, then 1.2, then 1.3 etc. As a result, companies must cut corners and continually make their products cheaper and cheaper and design them to last shorter and shorter times to try to increase those profits and satisfy shareholders.
Now we have a throw-away society with massive amounts of pollution, and waste with crappy crappy products that are designed to last only a few years at most.
The saying "They don't make them like they used to" is widely used for good reason and the stock market is the reason for that phrase holding so much truth.
Taking DELL private could be a good thing.
