Any C-levels, current or former, who were in charge during the unethical behaviour should be made to pay this. Either they knew or they should have known. Seize their assets, take them back to basic income and lifestyle and only then take the remainder of the fine from the company.

Yeah, I know this is a pipe dream. These people have their arms lodged so deep in politicians it makes their mouths flap, so it'll never happen, but it would stop this sort of behaviour right quick.
