One of the world’s richest men thinks we’re all working too much.

Mexico’s Carlos Slim, who is the world’s second richest person, called for a “radical overhaul” of the work week. He says we should be working 3-day work weeks, perhaps 11 hours a day. He envisions people working until they’re 70 or 75 but having more time off each week.

He believes the solution would make people happier, healthier, more productive and help solve the financial challenges of people living longer.

Actually sounds like a decent idea.
