Google's average total compensation per employee is much higher than that, around $300k IIRC. You also need to back out cost of revenue to get a more accurate picture of return.

But Google is irreparable and sinking fast. The goal is to return as much as possible to shareholders during 5 years window Google still has so shareholders can better allocate capital themselves. Every 124k/year is appreciated.

The average is meaningless. What matters from the company perspective is the additional revenue for the last employee.
