Au contraire, when my mother was growing up most ingredients were organic and free range by default and all your meals were hand made and free of synthetic additives.
There are charts which show the cratering of nutritional content of fresh produce over time so maybe not all goods and services of the past were total crap.
What people mean when they say farming in the past was “organic” is that crops would be grown in actual, non-metaphorical crap. You would collect a big pile of it, let it sit there stinking up the area, and then when it dried and decomposed enough you would spread an even layer of crap across your fields.
