I think it's about time that part of the public unable to think prudently about a lifelong debt had the living daylights scared out of them. A mortgage, unlike a credit card debt, is secured against the property - the mortgagors have it for upwards of 15 years.
The interest rates are still low and with some serious inflation problems on the horizon, they'll ultimately have to go up. So if people are borrowing wildly on credit cards too, they're going to run into trouble.
Scare them, if only for the sake of the children that inevitable creep into borrowers' lives. On that program I felt saddest for the young boy dragged into displacement by parents who hadn't bothered to think.
