I’m not sure what board you’re referring to… the one I saw was a list of tariffs to be imposed on individual countries. If there’s a board that showed deficit by country, it would also make sense from the context of reciprocal tariffs and the gap the US is trying to close with tariffs as the main tool.
I’m sure you’ll agree that many Americans do not understand economics; even people with economics degrees… just look at AOC.
Therefore, politicians will oftentimes simplify their messaging. The democrats have mastered it: the rich need to pay their fair share; my body my choice; people need to be paid a living wage; healthcare is a human right, etc. yet when pushed to explain, like what does “fair share” look like, you’ll get blank stares from people who parrot those slogans.
In Trump’s case, a good example is how they tout reciprocal tariffs because that’s easy to understand. But it’s far more nuances than that. Japan, for example, has pretty low tariffs on US goods BUT they’ve created regulatory barriers to entry which is why you rarely see an American car in Japan. Tariffs are being used to get them to the negotiating table to remove those non-tariff barriers.
