Me too, but it's very unlikely to happen. Payday loans (according to http://thehill.com/regulation/237538-borrowers-default-on-ne... and the study linked there) have a default rate of about 46% in the first two years, making them risky plays; to compensate for that, they have to increase interest rates and fees, which is a huge part of what makes them evil in the first place. Of course, the fact that 80% of payday loans are due to loan churn itself (paying off a payday loan with another) contributes to that in a big way, so maybe it could be done somehow.
I'd be interested in seeing a saner way of handling payday loans than exists right now, but I'm skeptical that it could be done in a way that isn't -- in some way -- predatory.
