Trump is playing a "who blinks first" game with these tariffs. If companies like Vietnam, with a purported 97% tariff on imports from the US, come to the post and say "hey, OK, we'll lower our tariffs on US imports to 25%, Trump will drop the applied tariff on goods coming from them. That is the idea. If they refuse to budge and all their products coming to the US are suddenly 45% more, they will sell A LOT less of their product. Trump kind of has a lot of countries by the balls right now.
The US citizens, at least from my point of view, seem to be the most wasteful and frivolous spenders on the planet-- much of which is enabled by very cheap import products. Take that away and the whole game changes, not just for the USA, but for most of world. This is going to be a wild ride, Im very curious to see how it plays out.
