Positive deposits are a great tool when you're in a relationship with a power dynamic like a teacher with students or a boss with employees. A sticker chart to get the pizza party is something we are all familiar with.

Where this falls apart is when it's a relationship that is supposed to be based on equality and shared responsibilities. It inherently assigns the power and authority to one side, the wife/mother in this case.

In my opinion, the only way a thing like this works is a straight up competition. Both their names need to be earning stickers and there needs to be a single prize to be won. BJs go both ways.
