They will have to pay damages im sure... the question is will it be enough? What does accountability look like? Is there any outcome that will sate the big government/nationalize contingent?
Damages are likely pointless. The person who made the decision did so because they believed that the short-term profits would matter more to their shareholders and their own bottom line than any future penalties, especially because they might not even be there when the penalties come.
I haven't thought about this a ton, but overall I'm thinking something like this:
* Decision-makers who engage in shady shyt in an essential industry should be barred from that industry. Whether it's planes or finances or tech, if you make a major screwup, you should be done. You know how easy it is for a teacher who commits a crime to lose their job and never be able to teach again? Or an athlete to never get picked up by a team again? But some of these business execs can do the most unholy crap and then jump right back into the mix. They should be done.
* When it's determined that shady shyt went down and they're talking about fines, they actually need to talk about
criminal consequences. If money was stolen from customers, that's theft. If customer's lives were put in danger, that's reckless endangerment. If customer's died, that's involuntary manslaughter. Screw the fines, most of the a$$holes stay rich anyway. Lock them up.
* When there are fines and damages, that money needs to be recovered from shareholders. Not the shareholders right now, the shareholders who were in charge when it happened. If you sell stolen goods, you have to cough that money back up even if you didn't know they were stolen. Well, if you profit from illegally boosted stocks, that should be considered stolen property, and it needs to be returned.
Hit that shyt right where the decisions are actually made. That's the only thing that will make them stand down.
