Could be, but there are diseconomies of scale as well as economies of scale in large organizations.

On a related note, the value of communications networks (email, IM, telephones, blogs, the post office) seem to increase on the order of n log (n) with respect to the number of users. One may even get negative value, because after something reaches a certain level of popularity, spammers start flocking to it and driving out legitimate communication. Consider all the junk mail you get - and note that junk faxes are illegal!

So I suspect our instincts are just plain noise when it comes to the value of joining large organizations.
