Should I sponsor 5 kids or give it all to 1 kid?

Usually when you give to a program like that, all the money doesn't go to the children. And they use it as they see fit. You don't get to decide. Some of it goes to run the foundation. I don't know anything about World Vision, but I do know that a lot of places like that are scams. I would do a lot of research before I sent my money.
