Ezra Klein had a contest to come up with alternatives to "strong" and "weak" as adjectives to describe high and low value dollars. He likes "import" and "export" dollars. I like "fat" dollar and "thin" dollar.
But observe the medium amount of human attention that had to swirl about the issue; that numerous people had to have to even think explicitly about it and think that there should be different adjectives in use and think up particular adjectives. So where did the original "strong" and "weak" adjectives come from? Was there any less a conscious effort to bring them into use?
