James Surowiecki wants one:
Some [critics of proper financial education] suggest that financial illiteracy is an example of what economists call “rational ignorance”inattention that is justified because the costs of paying attention outweigh the benefits. But few decisions affect us more directly than the ones we make about our money. Critics also argue that financial education may make people overconfident, and therefore more likely to make bad decisions. In fact, the reverse is true: the less people know, the more overconfident in their abilities they tend to be.
