Corporations hate competition.
They try to destroy their rivals as soon as they become powerful enough. Just look at Microsoft, whose operating system is used by most of the world. Or, J.D. Rockefeller, whose oil company wiped out almost all competition before anti-trust laws. It's ironic, that after the federal government broke up Standard Oil, its individual parts were more valuable than the whole. The United States Government made Rockefeller richer than he had ever dreamed of becoming.
