Philippe Van Parijs is a grown-up who thinks a lot about how we share things and make sure everyone has enough. He has a special way of looking at things called "Universal Basic Income" or UBI for short. UBI means that everyone gets a little bit of money, just for being a person.
Imagine you and your friend have a box of candies that you are trying to share. Sometimes, one of you might get more candies than the other. That might not be fair, and it might make one of you unhappy. UBI is like making sure that everyone gets a fair number of candies, even if they don't find as many as the other person.
Mr. Van Parijs wants to make sure everyone has enough food to eat, a place to live and other things they need to be healthy and happy. He thinks one way to do this is to give everyone a little bit of money every month, no matter what job they have or how much money they make.
Some people might think that's not a good idea because they worry about where all the money will come from. Mr. Van Parijs thinks it's important to make sure everyone is being treated fairly, even if it means changing how things have always been done in the past. He believes that everyone should be able to have a good life and do the things they love, without worrying about not having enough money.
