About a month ago I came across an interesting read that says that the stock market stats for the past 20 years have been showing that GM is "doing it wrong". [And that the airlines, other than Southwestern, aren't looking pretty.]
Now it seems that fivethirtyeight.com argue that the numbers show that GM's problems are 50 years in the making. Oops. Many of the comments are interesting too. They linked to a thoughtful blog post about GM management's "no we can't" mindset and why that will drown GM, bailout money or not.
