Very informative post, and for background, I am not an us citizen. I have no issue with the idea of small luxury because it's socialized, but I do have the impression that obesity is a huge issue in the US and these kind of consumption patterns cause reinforcement and lead to worse outcomes. I have nothing against cheap food and cheap calories(actually I think they are super useful) but I do think healthier people are an aim we, as a species, should target.
