Billionaire Jeff Greene, founder of Florida Sunshine Investments, attended this week’s World Economic Forum in Davos, Switzerland. During an interview at the forum, Greene was discussing what he predicts to be an upcoming “jobs crisis that will cause social unrest and radical politics,” Bloomberg reported.

“America’s lifestyle expectations are far too high and need to be adjusted so we have less things and a smaller, better existence,” said Greene. “We need to reinvent our whole system of life.”

Greene, who has a net worth of $3 billion according to Forbes, flew to Switzerland for the week, along with his wife, children, and the couple’s two nannies on Greene’s private jet.
