Growing up on Iowa farms in the 1960s and 1970s, I recall having dinner on non school days, like summer, and supper in the evening with family, as the norm. My dad would sometimes have dinner in the field, but usually the whole family was there. Today, an ever lower percentage of people farm and the industry has changed. With bigger farms and fewer people, consolidated school districts, and longer commutes, it is perhaps even more difficult for people who live in rural Iowa to, than for those who live in town, suburb, or city. Not that it is easy for most people or any longer the norm.
There was a pretty good special on IPTV 15-20 years ago where they interviewed people photographed by a former Iowa State student, from the 1920s through the 1960s, including about changes from that time to today.

My parents were the youngest in their families and my grandparents lived long, so I can relate to much of what this video is about. They talk some about food and changes in Iowa agriculture since then.
Meals of course were pretty important anyone doing much farm work.
If you watch the video to the end, one might draw an analogy with what the OP is about.
