Can you give some examples of this failing? Naively many examples of things improving that i know of were either very boring bureaucratic endeavors or required heavily involvement in bureaucracy. The Clean Air and Water Act, the FDA, the Civil Rights Act, all required people at the level of government or some other large social group to organize and plan things and make them happen. And thus you need people with the specific area knowledge and group connections in that area to make those things happen.
Or is this a mis-reading of your claim?
