Do they really? They may be intended to do that, but if you think from the basic law of supply and demand the effects are clear. This policy will lead to more expensive batteries, EVs and solar panels. This will be the effect. Policies can help, when they improve the competitiveness of the industry, usually when there is less regulation and taxation. Chinese EV's cost 10K, comparable US cost 25K. Yes, we can legislate to forbid these communist law-breaking people to stop selling us their cars. But the effect will be more old clunkers on the road, more pollution and less money to spend on something else. And the Chinese will build and sell them to the rest of the world and grow their companies to such size that the moment you remove the tariff US companies will be dead. To fight this only productivity and technology will help, not legislation. You can't legislate your way to a full belly. Profit should come from somewhere. And if the US hadn't had the US dollar as a reserve currency shit would have hit the fan much faster.
