It is from an extremely conservative publication, and is supposed to be a slam against "the left" - but to me it is more damning to the Kotch brothers than anything I have read: http://goo.gl/aqOd7 Read the parts that were quoted in Politico:
Ask Charles Koch what he thinks about Obama and he looks like he’s just bit into a lemon. ‘He’s a dedicated egalitarian,’ Charles said. ‘I’m not saying he’s a Marxist, but he’s internalized some Marxist models—that is, that business tends to be successful by exploiting its customers and workers.’ David agreed. ‘He’s the most radical president we’ve ever had as a nation … and has done more damage to the free enterprise system and long-term prosperity than any president we’ve ever had.’ David suggested the president’s radicalism was tied to his upbringing. ‘His father was a hard core economic socialist in Kenya … So he had sort of antibusiness, anti-free enterprise influences affecting him almost all his life. It just shows you what a person with a silver tongue can achieveWhat is so bad about being "egalitarian" anyway?
