Of the Fortune 500 in 1955, 88% (440) are out of business.
When the "owner" dies, >95% of the companies eventually go out of business. Boeing, Ford, Apple, etc., are exceptions to the rule.
This "reverence" that America has for CEO's is largely misplaced. Most of them are slowly running the companies into the ground.
Tim Cook is an exception. Hiring Tim, is probably, the best thing Stevo did for Apple.
