I actually wasn't trying to be pedantic.... I genuinely did not see the point that was being made. If they imposed a debt above and beyond everything he owned, then yeah... I can see how that is "and then some", but when I read the sentence, I was quite thoroughly baffled as to how that could have been without them taking things from other people (presumably relatives or something).
Now if I *were* to be pedantic, I might have pointed out that since the uncle was in a position to be giving that advice in the first place, it is patently obvious that they did *NOT* take everything that he owned.... since he still had his own life, and the wisdom he acquired through the experience being discussed, arguing that both of these are certainly just as much things that he owns as any material possessions could be.
But I'm not trying to be pedantic, so while I've admittedly mentioned it here in passing, I don't intend to dispute the point.
