Interestingly, CUNA the Credit Union National Association somehow used the study as a way to try to bash payday lending, despite the 36% APR cap on payday loans to members of the military and their family. Here is the CUNA article: http://www.cuna.org/newsnow/08/system052908-10.html?ref=hed .

If anything the shows at least a correlation suggesting the opposite. The federal government capped the rate on short term credit to members of the military, lenders stopped providing short term credit to military members , and now foreclosures are higher.
