A tariff can go both ways. There can be tariffs on both imports and exports. This bill may reduce tariffs on exports but tariffs can be raised by importing countries. All this may do in the long run is increase dumping excess production by other countries into the US market which will in turn destroy domestic industries. Read up on China’s solar panel and steel dumping. This has been tried before and the issue of dumping is why the tariffs came into existence. The only real result will be the loss of our industrial base, such as it is, loss of jobs and eventually a lowering of our standard of living even further.
