The minority shareholders used the state to get justice in court, with regards to what Ford was contractually required to provide them. That's the purpose of government/justice for all. That's exactly WHEN a minority should have power, when it's legally in the right!

Libertarianism - Wikipedia, the free encyclopedia
--advocate a state which is limited to protecting its citizens from aggression, theft, breach of contract, and fraud.
