> Blaming any problem of this magnitude on individuals is not reasonable.
This is just anecdotal, but I see this a LOT. The stubborn insistence that blame is paramount in any discussion and that the world should be made fair before action can be taken to improve one's life is a pretty substantial barrier to said improvement. Sometimes the deck is stacked, and working on unstacking the deck can happen in parallel with reacting to the world as it is now. Out of college, I had friends who made half as much as me and spent twice as much; income aside, we were both exposed to pretty much exactly the same environment, and somehow we made purchasing decisions that were completely swapped from what you'd expect. As the parent comment said, "Amazon needs to do better" too, but putting personal behavior outside of the realm of control of the individual isn't helping anyone, it's harming them.
I agree with your general point that simply wishing that people would do better for a behavorial issue at this scale is unlikely to do much, but I don't think that's implied by the GP comment's suggestion. There have been successful campaigns to cause large-scale behavioral shifts before[1], and recognizing personal choice as a potential mechanism of improvement doesn't mean we can't approach the problem in an intentional, structural manner.
Just an aside, but in all of this I'm taking on faith the power of advertising that the HN community at large seems to consistently think that we're helpless before; this has never been my experience; I don't care much about ads, I don't see any mechanism in which they could drive my purchase decisions, etc etc. To wit, I buy the cheapest option (that I haven't already tried and disliked) for cheap items and extensively research medium to high priced ones. There's no question that brand advertising affects my level of brand awareness, but it's _really_ not difficult at all to remove that factor from your purchasing decisions. If anything, my prior would be that all the people who blindly purchase based on brand awareness are shifting the value prop towards brands that are _less_ well-known, since theoretically they need to compete on something else (price, features, quality, whatever).
