You are looking at it the wrong way. You should start a deity where other people give you a billion dollars.
Joining a religion causes you give money, and takes credit for anything good that may happens to you.
Pat Robertson is getting a little long in the tooth, maybe Rodeo could step into his shoes and make a few billion in change.
Seems like there is never a shortage of people eager to give their money away to shysters in hopes of proving to God that they are worthy of entering the pearly gates of heaven.
