When I visit my elderly mom after several months, I can't quite understand how she's purchased all sorts of bunk from everywhere, not just Amazon. From church MLM sales, to random youtube ads that take her to a store front. While the things she has purchased isn't an absolute scam, they tend to either be low quality or far overpriced for the purchased price.
I do think that there is both a tech privilege that our cohort shares in both high compensation and a better tuned intuition as we tend to be the creators of many products and have a good smell test when it comes to how the sauce is made. The high comp allows for us to purchase the high quality, brand-name version of many products. While understanding the sauce behind a lot of stuff informs my internal heuristics of price, pictures, marketing, 1,3, and 4 star reviews.
I do get the impression that those that are scammed on Amazon tend to be the cohort that is looking for esoteric goods, bleeding edge folks, or just the generally non-privileged folks that will gamble on a $7 Amazon item rather than a $100 version of the thing.
