I agree... this is an interesting concept we should explore. As an analogy to the corporate veil, basically anything a person would do in their employment would generally be forgiven as "well, you've gotta make a living", unless it reaches a point where it's sufficiently morally wrong to still hold the person responsible for their actions on the job. For example, if their job were Winston Smith's (George Orwell character) job of editing historical news articles to distort the past, then we might say Winston is still personally responsible.
The difficulty here is holding CEOs responsible for crimes with "piercing the corporate veil" is holding a high level, powerful decision-maker, with options, responsible... rather than a person who might be trying to support 5 kids and some elderly parents, and couldn't just choose to sweep the street instead of working at the Ministry of Information for 6 figures.
If you spend the majority of your time working to abuse your fellow man, I don't respect that, and see no reason why I should.
That is not, and should not be accepted as, a "normal life".
