According to this youtube video by Patrick Boyle Patrick Boyle there is a lawsuit going on about a simpsons like bankruptcy. The allegation, as I understand it, is that Thai Foods, the 100% owner of Red Lobster, exerted "undue influence" such that Red Lobster offered an "all the shrimp you can eat" deal which was financially ruinous for Red Lobster and somewhat profitable for Thai Foods as they supplied the shrimp. The implication being that Red Lobster was failing anyway, and it was slightly better for the parent company for it to fail like this than for it too happen slower.
If the allegations and the corresponding implication was true, what would be wrong with this action? In whose interest are the 100% owners of a private company required to act if not their own?
