When we use "we"

I realize that most of usage of the word "we" is an euphemism. The purpose is either to appear "team-oriented" (as in single author research papers), or to shed responsibility (as in "what we really need to do is to bring people out of poverty.")

The latter case is more damaging, because it blinds people from the real party that needs be held accountable (be it UN, World Bank or IMF).
