If you flood our markets with cheap slave labor manufactured goods how do you think the average western manufacturing job is gonna react? Why do you think folks try to "make a career" off flipping burgers instead of getting a better paid job in manufacturing?
I think the topics are slightly different.
Cheap chinese goods flooding any market and taking market share away from local manufacturers is a problem in every country. But many other countries, especially rich developed countries like the US have managed to deal with this problem in a way that does not harm the local workforce.
The US government is within its rights to ban imports from a country if they think the quality is bad or if they are spying or if they employ slave labour. But the Huawei ban seems to be about none of those things, it is more about gaining economic supremacy over a country halfway around the world.
Also the reason menial job workers in the US cannot earn a livable wage is the terrible labour laws, rampant exploitative capitalism, and uncontrolled corporate lobbying; not chinese imports. You normally see these problems in a poorer country like mine, but you would expect a rich country like the US to do better in this regard.
