I understand the point, Griff. I think the airline industry does have much to answer for, but not necessarily for seat size. That's something of a red herring.
Case in point, the seats were built and measured at a time when people were generally thinner. They haven't kept up very well. Some seats are larger and roomier. First Class for instance, or even Business Class. They also cost more. To increase seat size means to fly fewer passengers, which affects their bottom dollar. In order to fly fewer passengers each trip, they will need to increase the rates exorbitantly, and people will complain about that,too.
But again, that's a red herring we're getting stuck on. Being overweight isn't something people choose to do. Being ignorant is sometimes something people choose to do. What annoys me the most is willful ignorance - having the tools and the knowledge, and refusing to look. But that's not most people, and there are many, many factors involved. It's not just food, because the mind and emotions are often involved.
