The problem today is that China and pretty much undermine any country's economy by subsidizing their domestic production.
How is that a problem? ${Country} has been subsidizing ${Local_Industry} since governments were first formed. I find it disingenious for Americans to complain about China subsidizing EV production. Specifically Americans. The American whose taxes bailed out Ford and GM. The only reason they survived is government support.
The bigger problem is Western governments have been insanely fucking shortsighted and *not* subsidised EV production enough, leaving it open to someone with more resources to start cornering the market. By the way the EU analysed the level of subsidy provided by the Chinese government and applied tariffs appropriately. The effect isn't as big as you make it out.
Like go look at how many Chinese EV's are just fake-sold and then sit in lots, fields, or are abandoned with no mileage.
And go look at the ones which aren't fake-sold. It seems like your view of the industry is based on shock news stories from the Daily Mail. If we all followed that it stands to reason that no one ever bought a Cybertruck, after all they were being abandoned in shopping mall lots as well. The reality is the stories about fake-sale EVs were not different than any story about cars when certain government deadlines hit. They were little more than a curious blip intended to meet short term numbers. Yes there's Chinese EVs which were fake-sold, and they are a tiny minority of the total production.
We should not be allowing China to dump stuff into North America
You say dump as if it's trash as opposed to what they actually are: very nice competently manufactured cars with great bang for buck. There's a reason why Ford's CEO drives a Chinese made EV, and then proceeded to publicly praise it. And it's not because his bonus is tied to tanking his share price.
Disclosure: I drive a Chinese made EV. A friend owns a Geely directly. Both are cars that I would buy again in a heartbeat. They are cars I chose over Audi, VW, Toyota, Tesla and Renault, all which were I test drove at the time. And while it wasn't a testdrive I dare say I'm absolutely shocked at the one time I had the true horrendous displeasure of driving a Mustang Mach-e, talk about "dump".
