No, people are idiots if they decided to get into debt without realising how to control it. If you can't drive you wouldn't drive a car on the road, if you did most people would call you an idiot...
But in this case it's more like the person couldn't drive, so booked lessons with a driving instructor, who after one lesson tells them they are a brilliant driver and books them into a test, knowing full well they can't drive. Why shouldn't they believe the instructor?
