You seem to have the persistent misunderstanding common among many of a generally leftist persuasion as to what exactly "limited liability" means.  All it means is that the simple act of being a shareholder in a corporation does not by itself open you to liability for what the corporation did (the operative theory being that you as a shareholder don't have sufficient control over the micro-level doings of the corporation).  It does not mean that the corporation, its officers, and employees have any limits on their liability for the actions of the corporation or its agents.
