So USA tariffs 200 countries.
The 200 countries do it back.
So the US imposes a tax on all the goods they import from foreign countries and the US citizens have to pay, how does it show the other 200 countries also do the same, they can import things from somewhere else, and it's the US citizens who pays more for the goods.
And speaking of other countries, if they can't source goods from any other countries so they will surely retaliate with USA and impose a tax to the exporters of US citizens which will cost US citizens too. Well, this is not good for anyone but for governments.
It don't actually work the way you thought, if the US is paying more, why are the exporting countries retaliating by imposing similar high tariffs on goods going to the US,? It then means that these countries are also paying more.
Economically speaking, let me bring to your knowledge in little ways the effects of high tariffs, though it is on both countries involved, but these countries are more effected than the US. The effects includes:
1.There will be decline in consumption, increase domestic productions
2. Increase government revenue
3. Protect domestic productions and jobs
4. Protect national interest
Now, one negative effects of tariff war is higher consumer prices. However, on the current US imposition of tariff to some countries, the impacts of the tariff are on the exporting countries and less on the US economy.
