Can it not be both ?
Ah scrolling down I see that's been asked.
It's less irresponsible lending though as the chances are, taking into consideration the risks, I'm sure they made an overall profit as they expected to do.They aren't concerned with whether one or other individual gets themselves into the mire.
It may be immoral lending though. Taking advantage of the desperate or the daft, neither of which have a government prepared to protect them, due to ideological reasons..
