The Americans have a huge trade deficit because successive governments swallowed whole the concept of allowing corporations that own or control manufacturing interests to -  move production to countries with subsistence wage rates, few if any workplace health and safety standards or environmental regulations. Then having the gall to import the  same products back into the USA at the same or higher prices fully expecting the now former employees to continue consuming what they used to build. This has happened in Canada as well.
Aggressive and disrespectful actions like that should have been met with stiff punitive import tariffs and the  political and administrative brain trust that supported it needed to be called out.

This is now happening thanks to President Trump.
