This is a minor nitpick, and it does not really concern the overall point you try make in the post, but it is incorrect to use the chart of "Share of Disposable Personal Income spent on food in the United States" as lone evidence for the claim that Americans are eating out more. These results would also be perfectly consistent, for example, with rising costs in "Food away from home", and falling/stagnant costs with "Food at home", all with no fluctuation in the actual proportion of meals that an American eats away from home vs at home. More importantly, even knowing both prices rise (as evidenced by the following chart) does not fully complete the picture if failing to also provide a baseline value for these. Note I don't actually doubt for a second that it is true (that Americans are eating out more)!
