I think debtors will far more often be middle and upper class than lower class. The most indebted of the poor might have tens of thousands of dollars of credit card debt, but that doesn't really stack up against a $600,000 mortgage. Also in this day and age of getting your credit checked for everything it seems like a lot of poor people probably have fairly restricted access to loans.
