This gold from wallstreetbets:

Soooo is the tariffs charged to the United States really a ratio of the trade imbalance?? For example Vietnam imported roughly 14.6 billion in goods from the United States, and we imported around 146 billion, so thus they have decided tariffs are 90% to the United States…thus we are putting a tariff on them of half of that…which means we are literally tariffing the goods we either a)need more or b) get more efficiently at a higher rate? That may be the absolute dumbest way to create a tariff policy I could imagine if that is the case…which it looks to be.
