But this IRS scam is so stupid and transparent that anyone who feel for it has to be so stupid that they really are a menace to society.
If you were talking about people our age, you'd be right. The problem is that these people largely prey on the elderly, many of whom are much less street-smart than folks decades younger. They're from a generation born when these sorts of scams were relatively rare, so if somebody called saying they were from the IRS, they probably were from the IRS—particularly if they have lots of your personal information. It isn't easy to teach college-age folks how to reliably recognize social engineering, much less the elderly. This goes double if they have any sort of mild dementia.
These people prey on the helpless. That makes them utterly inhuman in my book.
