With discussion of income inequality reaching a fever pitch—from New York City Mayor Bill de Blasio's "tale of two cities" message to the headline-grabbing sermons of Pope Francis—former Goldman Sachs asset management chairman Jim O'Neill believes the global economy could be at a tipping point.
"I wonder if we could be in the very early stages of a redistribution of wealth from capital back to mass income through government policies, whether it be from taxes or things being done to boost minimum wages," O'Neill told CNBC's "Squawk on the Street" on Wednesday.

O'Neill's comments come as income inequality becomes a hot-button issue across the globe.

Aside from the gap between rich and poor, O'Neill told CNBC that investors should watch rising interest rates and bond yields, and expect the U.S.to continue moving toward energy independence, causing it to drive less global growth. A perennial fear of central banks becoming less generous should also affect markets, he said.
"The U.S. is not going to be the same driver for the rest of the world," O'Neill said. "Because it's not soaking in anything quite like the same degree of [oil] imports that it once did."
