Or maybe there are more things using the same tactics / scammer's reach keeps increasing.

My parents "fell" for fundamentalism early (as kids - raised in it), for televangelists in their 40s, and Fox News in their 70s/80s. Fox News so recently only because they didn't get it very often until about 10 years ago when they moved into a retirement home (didn't have cable before that).

Right that's why I qualified that with "things they didn't used to fall for".
