Prior to this form of social insurance, the owners of a business were legally liable with their personal wealth for damages the business might have inflicted on others. With limited liability, the corporation’s shareholders are liable only up to their equity stake in the company. ... Beyond that, someone else in society — often the taxpayer — bears the financial risk for damages attributable to the corporation.
One wonders how many business executives and members of chambers of commerce ... realize that the limited liability of shareholders is social insurance.Harvard business professor David Moss, quoted at The Econmist's View, When the Going gets Tough, the Tough Run to the Government.
