It's also incredibly stupid that they tariff components.
If a US company wants to build a dishwasher then they're probably going to have to buy some parts from China, because the US lacks vertical integration, except they're not going to because those parts are also tariffed. So you might as well just make the dishwasher in China and pay a single tariff on the whole thing.
