"Democracy is broken" means that the will of the people is largely ignored, regardless of who they elect. This has been demonstrated to be the case in the US [1].
What's wrong with government "increasing" as society becomes more specialized and complicated?
And not everyone thinks that way, so it's not a place to "start" when talking about democracy.
