Management
A medical condition - and the professional field opened upon contraction - which nullifies or in severe cases reverses the normal causative effects of gaining skill in an area as experience with that area also grows, as well as inverting the pay-to-productivity ratio.
Example:
Bob got management and within 6 months had forgotten everything he had learned in his 10 years as a developer. He can't write a line of code anymore, but now he makes twice as much as he did before!
