I prefer jail time for companies. The entire operation has to shut down for a set period of time. No money going in or out. No one can work. No one can open their laptop. No one can go in the office. No one can discuss business. No new contracts signed.
If corporations have the same rights as humans, make them suffer the same consequences.
The effective outcome of corporate jailtime is that the company is instantly destroyed. There are no companies that would survive being shit down for years. Shareholders would be left with nothing.
And if people would be out of jobs - good. It would stop people from working for companies that don't provide transparency into the legality of their operations.
