These complaints seem orthogonal to the question of China using dumping as a tactic to dominate a market. Even if you thought the US auto industry was very healthy and well run, it could still be existentially affected by a huge actor with near infinite money like the CCP dumping
Only one country can print the world's reserve currency from thin air and it's not China nor the CCP. Why doesn't the US counter-dump then? Spoil the rest of us with affordable EVs and hasten humanity's transition away from ICE vehicles.
