His father, Fred Koch, was a staunch libertarian and an early member of the John Birch Society, as was Charles Koch for a period of his life. Like his father, Charles is also an ardent supporter of libertarian and conservative organizations. He is a co-founder of the Cato Institute, the Chairman of the Institute for Humane Studies, and has sponsored multiple conferences for entrepreneurs to encourage them to fund free-market groups. Charles has even applied his libertarian ideology to the structure of Koch Industries, using his own trademarked “Market Based Management” to run the entire company. "Just as central planning is a failure in running government, so it is at the level of the firm," says Charles.
