i personally know businesses in the US to make profit they have no choice but to import from China. I have a friend he is in import/ export and a major supplier to walmart. He tried looking around the world for better deals but no luck, that's why walmart is called little China.. 😀
Slow down even that was and will be temporary but shutdown is impossible. It's like standing in front of a roaring train trying to slow it down. China is a giant.
