The value of the labor managed by those leaders was over 100X greater than $415 million. Unprofitable is not the right term here (something ethical instead?).
The question is if the money those companies saved by illegally depressing wages was greater than the $415 million cost of the settlement, plus the bad press of the criminal investigation by the DOJ.
I don't think it is as clear cut as this comment makes out. What they did was come to an illegal agreement not to poach employees from each other. There are multiple reasons why that could be good for a company, and I doubt 'reducing wages' is close to the top of that list.
But ethics are important in leadership - I just think the case here isn't as simple as it is made out.
Both parts of the thing you were replying to seem relevant to me.
