im not saying that we dont export more than cuba (i mean given population size, thats to be expected), its just that what yhey can supply for theirselves internally is enough to sustain their own use, at worst, their exports are worse, but they arent just competing against thr U. S in terms of exports so thats more or less moot point, given Brazil on its own is larger and a reasonable distance.

the U.S would have to shift a significant portion of its rice specifically to Cuba if it wanted to disrupt prices there, and that considers that rice is the main carb they intake, which theres a bunch of other carbs they grow in country for their own consumption to move over to if necessary.

their economy if not able to compete would switch from being less export of produce to a heavier focus on tourism similar to other carribean nations.
