Infinite banking is not a bank gimmick

When I first heard about infinite banking, I thought it was just another bank gimmick.   It was only when hubs and I bought whole life insurance policies that I understood what it was.  The agent explained to us that we could borrow from our policies.  Should we need money in the future we could use it as a loan that we need to pay back with interest.   Well for me that's a great idea.  It's not like making a fool of myself by borrowing my own money and paying it back with interest.  It's just like banking and making your money grow.  Why would you make loan companies richer if you can make your money grow?
