The USA has become too dependent on the cheap products it gets from China. In the face of the high volumes of people stricken by CoronaVirus it was not able to supply enough face masks. In particular, the Federal Emergency Management Agency (FEMA) has in the past provided temporary shelters (e.g., trailers) and other products to victims of natural disasters, but the nature of the supplies needed to deal with the CoronaVirus was so different that potential suppliers were unprepared to provide sufficient quantities of appropriate items. To make matters worse, President Trump and 3M were feuding because he used the United States’ Defense Production Act to prevent shipments of US-made face masks to Canada or other countries. Fortunately, Trump and 3M changed their minds, though Canada and other countries might not be happy because they would be getting the less-effective face masks made by 3M whereas Americans would get the more-effective models imported from China.
