Pushing a liberal social agenda is the last thing you'd expect to see on CNBC's "Squawk on the Street." But the network's June 16 mid-morning show featured a segment praising the California Supreme Court for legalizing same-sex marriage because of a predicted economic benefit.

"This time around, one study expects over 100,000 gay couples will tie the knot, providing a boost to California's ailing economy hit hard by the real estate foreclosure meltdown," CNBC Silicon Valley Bureau Chief Jim Goldman said.

Goldman cited data from the pro-gay Williams Institute, a division of the University of California Los Angeles School of Law. According to its Web site, the Williams Institute "advances sexual orientation law and public policy through rigorous, independent research and scholarship, and disseminates it to judges, legislators, policymakers, media and the public."
