I didn't think I'd watch the whole 20 minutes, but here I am! And it was fascinating, awesome, and scary.
I agree with all of his criticisms except for one -- when he said something like "trying to collect on the debt of a deceased person is the scummiest thing there is."
Well, it depends on the circumstances. Is it a valid debt?
In my job I often work with people who are eligible for some kind of assistance benefit (social security, life insurance, disability, etc.). We had a guy who we had been trying to get ahold of for about a year, never returned calls, never replied to letters.
Eventually find out he died. After his death, his daughter calls and tells us essentially that her dad was an irresponsible jerk who had been intentionally withholding information from us for 10 or so months that caused us to overpay him.
I don't think in a situation like that there's anything wrong with trying to make things right by collecting a debt. I do understand that might be the exception rather than the rule, though.
