I understand why Trump's implementing these tariffs. In his inauguration speech, he said he was going to create an External Revenue Service (ERS) so that by gaining more revenue through tariffs, we Americans would have to pay less money in taxes. He also wants to increase the number of products made in America, which would create more jobs and reduce unemployment.
Prices might increase in the short run, but I believe they'll decrease in the long run. Sometimes you have to make things worse before you can make them better.
