Can somebody explain why it is bad for the United States to have tarriffs on goods made in other countries being imported into this country? Yet at the same time other countries have imposed tarriffs on goods produced in the United States that are exported to other countries for a long period of time.

I have seen a couple of charts listing tarriff percentage charges for goods exported into other countries versus tarriffs on goods exported to the United States. Most situations the tarriffs the United Sates charge other countries are lower, some are significantly lower, than what the United States is charged by other countries.

What is wrong with the United Sates trying to level the playing field?
