One thing looks good on a balance sheet and the other requires thinking beyond the balance sheet. The vast majority of companies and middle/upper management are really only looking to the short term and their own individual resume. If the cows don't come home to roost (oops mixed the metaphor) for a few years and Jim has already moved from Company A to Company C by then, and failed upward three places on the corporate ladder, why should they care?

Feels like most huge corporations do an executive shakeup every 5-8 years or so, and they shake some people out, but those people just get picked back up by someone else fresh off their own executive shuffle.
