Timothy, I think most in this forum agree with you that people aren't disposable.  I've also found that generally organizations don't have opinions, they simply have people who do.  I think the people who have shared that proverb with you should either leave, like you seem to have done, or complain about it to someone who can do something about it, like their manager.

In contrast too, I think we solve the problem not by focusing on the problem or the consequences, but by focusing on the solution.  Would you care to share about organizations that appreciate and empower their people?  Do you know of any companies who attract talent?  In my local area, there are a couple of large employers, like Bama Companies and QuikTrip who consistently win awards for how they treat their people and the positive contribution they make to the area.  For me, I tend to drive in the direction of my focus.  So I like to focus on those that do things well.
