They are saying that in bureaucratic countries there is not a single entity that can be held accountable, which means that "bad" decisions, are not easily undone. Likewise it means that "good" decisions are hard to change. It is a statement about the momentum of change, not about it's worth or intention.

There is no further comparison made between these governmental forms and how they affect their subjects.

Why would you create such a blatant red herring?
