This is why lists of "elderly owned" phone numbers go for so much on the black/gray market. The cost of running these scams is so low that they spam everyone with their bait, but I suspect the real cash cows are elderly people who have large savings / Social Security checks.
Part of the problem is that it is super difficult to teach a parent or grandparent what inspect element even is without delving deep into Web infrastructure and how browsers work...very complicated, technical explanations. Simplification works to a point, but if you just tell them "don't trust what you see on the screen" they'll ignore actually important warnings, blast through alert boxes faster than they can read them, and when your next lesson includes "look for the green padlock next to each address" they'll just get even more confused since, you know, you just told them not to trust anything.
