"For many years, I, my family and our company have contributed to a variety of intellectual and political causes working to solve" federal and state budget problems, Charles Koch wrote in a Wall Street Journal commentary. "Because of our activism, we've been vilified by various groups. Despite this criticism, we're determined to keep contributing and standing up for those politicians, like Wisconsin Gov. Scott Walker, who are taking these challenges seriously." Koch, the chairman and CEO of Wichita-based Koch Industries, criticized both parties for tiptoeing around the issue of overspending. "There have been few serious proposals for necessary cuts in military and entitlement programs, even though these account for about three-fourths of all federal spending," he wrote. And though he acknowledged that Koch companies have participated in "market-distorting" subsidy programs, he criticized other companies for not being outspoken in defense of economic freedom. "We see far too many businesses that paint their tails white and run with the antelope," he wrote.
