Former United States President Barack Obama believes that ballooning wealth inequality is a threat to society, and that those who have the means should help those who are less fortunate.

“Right now I’m actually surprised by how much money I got,” the 44th President said in his address to more than 10,000 people gathered in Johannesburg, South Africa, on Tuesday. “There’s only so much you can eat. There’s only so big a house you can have. There’s only so many nice trips you can take. I mean, it’s enough.”
