I feel like people often forget that the law clearly holds people responsible for things that they did intentionally and willfully. Which is to say, being able to jail C-level executives would not allow you to be jailed because your employees did something without telling you. It would allow you to be jailed when you make a decision that gets people killed or causes some other significant harm.

Instead of fining the nebulous company that you are a part of, you would be held responsible for your choices.
