it's not even about criticizing capitalism (though there's lots to say about that) as it is about criticizing the philosophy of managerialism that Munger's comment exemplifies.

to me it seems like nothing less than an elite member of a specific social class congratulating himself, and by proxy those he represents, for being a cog in the big machine. Charlie's cog is a very big one indeed so he can make comments like that with no irony or self-awareness.
