Trivia for you: there are more payday lenders in America than there are McDonalds and Starbucks combined, even though they are banned in 13 states. Really interesting story over at Hit and Run: "How Payday Lenders and Check Cashers Help the Poor - An Ivy League professor went to work in the industry to figure out why so many Americans choose to remain "unbanked."."
Watch the video. There's a reason there are so many payday lenders and check cashers: for a large number of people there's really no alternative for them at traditional banks. They can't wait for the "float" of regular banks - they need cash now for a variety of reasons.
