If they can't work another executive job, they can't go around harming other businesses and people. The first thing that should happen is that the bad actions stop happening, by whatever means necessary. Justice can come later if that's truly necessary.

I think the GP is on the right track. Business leaders need fear consequences, so they moderate their behavior, and that means messages must be sent. It would be perfect to have some fortune 100 CEO go to Davos one year, then return the next in a prison jumpsuit to tell all the collected elites about what it feels like to be utterly ruined. Then do it again and again until the message gets through.

There's no need to resort to extreme measure, unless things are truly beyond the pale. It matters far more that regulations are enforced and consequences are enacted. Consequence don't need to be dire, unless actions are so beyond the pale that it required criminal investigations and consequences. If things escalated to the point of criminal investigation, your system isn't working.

The first step is early detection, enforcement, and auditing. The FAA should be beefed up so that they can rely on their own agents for enforcing the rules, together with the ability to ramp up fines, stop production, and other gradual escalation until there are compliance to regulation.
