Apart from lack of interest in dis-incentivizing this behavior, two possible reasons come to mind - why managers like these exist: 1. (Nature) Some of them were just tuned that way since childhood. 2. (Nurture) When these managers were junior employees, some/all of their past managers micro-managed them similarly, which built up resentment inside them and instead of rejecting these traits & becoming a better human, these junior employees decided to 'Pay it forward' in the worst way possible and ergo, continue the vicious cycle.
