One of the key issues for me is that most workers prefer a stable (low) pay every month rather than a variable pay proportional to the company's current revenue.

Seemingly everyone prefers to rent-seek and sit around 8 hours per day doing the bare minimum. The incentives are so broken. 

 yep

why would you punish a worker giving you the answer in 30 minutes, and make him spend hours upon hours on it on paper to get the same reward for it
