Developed countries like the U.S. should take care of those in desperate need, said Warren Buffett, chairman and CEO of Berkshire Hathaway.
"In a country with $65,000 in GDP per capita ... you do take care of the people that for one reason or another ... have become roadkill," Buffett told CNBC's Becky Quick at The Gatehouse's Hands Up for Success luncheon in Grapevine, Texas. "We are prosperity. We should take care of people who've become roadkill because of something beyond their control... I think that's the obligation of a rich country," he said.
Buffett said the benefit of free trade is rather "invisible," and in fact the policy has done damage to some workers.
