edit: not really difficult to do, you can compare the salaries per region (averages, median and distributions) pre and post lawsuit.
Where does this number come from? When the wage fixing agreement was canceled, Google immediately issued an across the board raise, and compensation has increase very quickly since then. That's 15k software devs right there, not even considering the second-order effects, which are surely non-zero.
Can you discuss the second-order effects? They're not apparent to me.
Edit: HN isn't allowing me to reply to you. Thanks for correcting my estimate. I was way off.
As for the second order effects, do you know a hiring manager? Ask them about how competitive offers have changed since the no-poach agreement was canceled. The effect is much larger than just having to keep up with the across the board raise Google gave to their employees when the agreement expired, which was itself non-trivial.
In this case, it's probably best to match the malfeasance with the risk. What do you think he is likely to harm within government program management?
Edit: my original estimate of 15k was way off base. A subsequent poster has suggested it was a minimum of 64,000, probably substantially more.
