To alleviate traffic and fight pollution, Luxembourg is planning on becoming the first country in the world to make public transportation free for everyone.

Under the coalition government's plan, starting next summer, tickets will no longer be necessary for trains, trams, and buses. Prime Minister Xavier Bettel was sworn in for a second term on Wednesday, and during the campaign, said he would focus on the environment.

Luxembourg has a population of 600,000, with 110,000 people living in the capital Luxembourg City, but roughly 200,000 commuters drive in daily for work from Belgium, France, and Germany. A 2016 study found that Luxembourg City had some of the worst congestion in the world, with drivers there spending an average of 33 hours a year sitting in traffic. The government still has to finalize the plan, including deciding if people should pay for first- and second-class compartments on trains. Catherine Garcia

Carlos Slim — the richest man in the world — has a novel idea: Instead of working five (or more) days a week, bring it down to three.

"You should have more time for you during all of your life, not when you're 65 and retired," he told CNNMoney. But don't get too excited: Slim also thinks shifts should last 11 hours, and people should wait and retire at 75.

Slim got his start investing in bonds at age 12 and stocks a year or so later, and today he's worth more than $80 billion. He thinks that having a shorter work week would make it easier for young people to enter the work force, and older employees could pass down the things they've learned along the way. "It's a society of knowledge and experience," he said. "You have better experience and knowledge when you are 60, 65, and 70." Catherine Garcia
