In my last essay on the Baby Boomers I said that it was okay to pick on them if it's just once a year. That was two years ago, so it's more than fair to pick things up again. This is a good time to comment too, as at the time of writing we are in the midst of the "burrito discourse" on social media. I'd link to the relevant posts, but searching social media is a huge headache and the only way to reliably save this stuff is through screenshots that are trivial to doctor (and thus aren't really reliable records.) So people of the future, you'll have to just take my word on what is being discussed.
Basically as far as I can tell the kerfuffle started in response to complaints about high food prices, both in terms of restaurants and groceries. At some point the conversation centered on Chipotle burritos now being around $10. Then someone responded that he was able to make a burrito meal for eight people for only $20 by getting the stuff from the grocery store himself, which led to people analyzing just how cheap and crap of ingredients and portions you would need to select to make that meal possible. Usually this started with people claiming it was trivial, only to cheap out more and more with presented with actual numbers. (What, you're being 90/10 lean/fat beef? Come on, don't get such a luxury item! Everyone always buys 70/30. What, you're expecting a third pound of beef per person? No, we mean one pound of beef for all eight people, etc.) It got pretty silly.
Even though this is called the "burrito discourse" as a shorthand, it really was a discussion of affordibility in general. That is, someone would say "I used to be able to afford X and now I can't" and would get the response (largely from boomers, though to be fair some members of Gen Jones and Gen X also ddi this) that "you were being too wasteful in wanting X to begin with. Here is a way you can get something else for cheaper. And woops, turns out that even my alternative is too expensive, but here's something crappier that might be affordable." The "X" could be fast food meals, various types of grocery store items (particualrly meat), cars, housing, etc. The specific good varied, but the conversation was always the same.
