Quite simply, any conclusion of this saga that doesn't end with 3M and fellow companies utterly erased and their assets sold off to more responsible stewards to pay for remediation and cleanup efforts, including piercing the corporate veil for a lot of the owners, is a miscarriage of justice. You cannot be allowed, as a private entity, to knowingly pollute.... everything, and still be allowed to conduct business. You have made it abundantly clear that you will harm others for profit, and we should be aggressively destroying any company that does so.
You have no natural right to a profit at other's expense, and we should stop pretending that these companies are following the rule of the law with these settlements. No part of any law says you have to let malicious companies continue to operate because they are big and have a lot of money. Bankruptcy is an important and necessary part of a healthy market.
