Its corporation. Morals are not really the top priority. The results are.
I don't think levemi is saying anything about morals -- rather, that results will be better if employees are cooperating with one another rather than playing zero-sum games in the hope of missing the next round of layoffs.
But it could just as easily be argued that a highly political environment which necessitates such behaviors leads to poor morale, quality employees leaving etc. etc. which couldn't be good for the company long term...
I would say it all depends on the point of view of the people in charge. The reality is what they decide and whats their take on that.
