Why don't we complain?

I found this article very interesting.  It discussed the reasons why humans do not complain.  One reason could be fear of negative repercussions from peers or the person in which you are complaining to.  Many people have a predisposition to think that complaining is worse than being uncomfortable and will therefore accept being uncomfortable.  I think that if you are nice about the problem no one will be able to say you were out of line, they might even be happy that someone had the nerve to say something.

Another reason why many people may not complain in an unpleasant situation is because of the by stander effect.  If they are uncomfortable or unhappy, at what point will they take it upon themselves to remedy the situation?  It would be at the point when they realized that no one else was going to do it.  Human kind is predisposed to believe that other people will take the lead in situations and therefore, much of the time nothing gets done. 

A third alternative could be because of sheer shyness.  This is the hardest to combat, because it is a trait of the person that is very hard to manipulate.  However, I shy person may be annoyed by a situation but never get to the point of thinking about doing something to change it, therefore avoiding the discomfort of compliance.

The author of this article states that at the point when humans no longer complain, we will become automatons, incapable of feeling.  I wonder what others think of this conclusion.  Does compliance lead to lifeless humans? Is it right to always complain when faced with imperfect situations?
