It is actually more than likely to get 2x the throughput when paying for better talent. The bottom of the talent pool is saturated with coasters who never invest in learning. I am seeing way more than 2x. There is also a cumulative factor when you get most of your employess in that caliber. Lastly, there is a limit on what a low talent pool can achieve regardless of the numbers. 1,000 people with my physics skill won't invent the theory of relativity. 10,000 coasters can't invent page rank.
