Yeah, it's a mistake to think that a meeting is always the most efficient way of doing things. Every meeting held costs the company thousands of dollars as people are not able to do other things during it, and so many companies just don't even think twice about adding anyone and everyone and don't think of how much it's costing them in productivity lost to other things because they just always assume that meetings are the best way to get things done.

I think it would be better if meetings were seen as the expensive beasts they are and only the bare minimum of people that can attend it, should attend it, and it should be considered (especially with routine meetings) whether or not the meetings even need to be held in the first place.
