Peak Productivity — the point at which more time is spent on bureaucracy than on actually getting work done. 

It makes people less creative. Being trained into hierarchical submission diminishes creativity, an inherently rebellious act of imagining that which is not.

It makes people dumber. One recent study suggests that working for more than 25 hours a week can impair intelligence as we age. Even sitting at your desk all day might be making you dumber.

The Stupidity Paradox points out that a number of aspects of corporate behaviour encourage and reward stupidity: 

• Entry-level positions consist of routine tasks that seem pointless. 
• The incentives of the system reward those who keep clients happy and don’t rock the boat. 
• Asking difficult questions or picking at assumptions is seen as dangerous and disruptive. 
• Toeing the corporate line gets you promoted.
• Being seen doing long hours is often more valued than actual work.
