Corporate death penalty. I want to see these groups of "shareholder value" get destroyed. Equal to a damage of a normal death penalty to an individual. Spread the organization to the winds.
If that means a "company" becomes smaller, with more isolated crews run by their own leadership, good.
I could see there being an issue with too much forced collusion if companies are too small to operate. Like how a lot of companies put all the blame on a profitless, employee-less "subsidiary" and say "oh no, we can't pay a fine, we have no money. We gave all our profits to Company Inc Ltd, we're just Company Inc." We'd need to fix that first. Then corporate death penalty. Which I believe does exist but isn't used very often. I think some court rulings have forbidden operations in certain states.
