The worst corp I can think of is Nestlé, these pieces of shit have done a lot of environmental damage and have been known to engage or complicit in slavery.
Erasing Nestlé is like erasing the infectious boil on a human body.
What foul company would you erase for good and why?
All of them. Limit the size, ban acquisitions. Break up monopolies. They’ve never been good for everyone and just become exploitative.
See Dutch East India company, the worst of the lot who was a corporation that had their own military. Learn from history so mistakes are not repeated again.
