Nor should it be. Lenders like to conveniently forget: the risk of default is the reason they charge interest. If there was no risk of default, you couldn't really justify charging much interest, could you?
Issuing a loan is a business arrangement, and default is one of several clearly defined ways of exiting that arrangement. Lenders have been very successful in their attempt to smear default as some sort of moral failure. Like you're some kind of bad person for making a sensible business decision!
