To some degree yes, but truthfully, I don't think the "IHOP Breakfast" for lack of a better term is unique to non-farmers. My grandparents were farmers, their neighbors are farmers, their parents were farmers, and they grew up on short-stacks, sausage, oatmeal, the works.

I never suggested that the IHOP breakfast is the only breakfast Americans eat, but I do posit if you grab a person on the street and ask them what is "breakfast food", you'll hear the IHOP breakfast in some way
