That's actually an interesting idea. In life fines are definitely not enough to prevent normal citizens from doing crimes. Jail time and prison sure is. Maybe a system modeled after Nordic prisons would be good. Instead of fines, perhaps a government agency could be formed that "jails" a corporation. Comes in and rehabilitates the corp. Making sure it follows all applicable laws, not scamming it's employees, and auditing everything. But not from like an outside in approach. But from a "were the CEO type approach". If that's too light then maybe am American approach to jail. They are seized and held for a certain amount of time. Offices must close. Their accounts are frozen. No business can be done.
