The dominant business school philosophy in the West is that 1. any reputation you have with your customers is a monetary asset and 2. therefore you should sell it for profit because it's greater than the long term expected monetary value according to a simple time-value of money calculation, especially because of the lag before your customers figure out you've sold them out.

#1 on its own isn't so bad, you should indeed treat reputation as a valuable asset, but the way their style of logic invariably jumps to "and therefore you should sell, sell, sell it!" is the source of the problems we see. Especially because they're likely to jump jobs before the consequences occur. We really ought to have a culture of looking askance at executives and decision makers who never spend more than 2 years at a job, rather than celebrating them. If they've never had to live with the effects of their decisions they're really just a fresh-out-of-college person with 10 instances of the same two years of experience.
