USSR bartered machinery for bananas or sugar with Vietnam and Cuba because they lacked hard currency. I heard rumors that the rate was 1:1 by weight but I haven’t been able to find evidence. It’s probably just a widespread myth making fun of how dumb the USSR’s policies were and the banana scarcity.

















A slightly less dumb idea would be to tax food by calorie content. In ages of famine, that tends to be the main factor in its cost, after all, and when obesity is rampant, it could make people more aware of their diet. Artificial sweeteners and other low-energy alternatives would become way more viable. Of course, this is impractical as it would inadvertently cause massive misrepresentation of calorie count (even if the <5 cal/serving ≈ 0 cal loophole is closed).
