The grass is always greener on the other side of the fence.
The problem with cog in the machine analogies is that people only think of the plus sides of having more input in decision making processes.
What people generally ignore is the added responsibility and liability that comes with being more invested in the decision making process. In my experience, after you start holding people accountable for making the wrong decisions, most people quickly go back to being happy about being a cog in the machine and taking orders from someone else. For the few who enjoy calling the shots and accepting the blame when things go wrong, you can always move up into management.
