Electric cars have between 5k and 10k fewer parts than non-electric counterparts, so why so much?

that make subsidies beneficial to the national interest...in this case the issue is the need for a rapid shift away from burning fossil fuels...and from preserving them.

I've attached a link on this issue from 'Investopedia', and here is an excerpt of the key points...
-------------------------
KEY TAKEAWAYS
>Subsidies are payments, tax breaks, or other forms of economic support given by governments to certain industries or economic sectors.
>The goal of subsidies is to aid or support what are deemed to be key parts of the economy or national infrastructure.
>While subsidies may have a direct positive impact on the particular industry or companies involved, economists argue that subsidies work against free trade and create market inefficiencies.
------------------------
Given the global acceptance of Climate Change as a threat to all nations, it is deemed essential that we shift our energy strategy...and attendant infrastructure away from fossil fuels...and waiting for a widely disparate market to coalesce around a common solution is IMO foolhardy...therefore, if falls upon government to provide the necessary 'incentives' that will more quickly effect those changes...simple as that...it's URGENT...whether you like it or not, 193+ nations agree.

Nigro explained that the lead time for EV manufacturers to extract minerals and build batteries in various countries can take several years.

But this is a case of the government trying to accomplish three things at once, Gleckman said.

“It’s trying to encourage people to buy EVs, it is limiting the benefits to t eople making less than a certain amount of money — it’s trying to be progressive in the design of the tax code,” he said. “And it’s also trying to impose a ‘Made in America’ standard on the cars.”

That last piece — ensuring that the sourcing of materials for these vehicles is sound, sustainable and beneficial to the nation’s economy and security — is critically important, according to Nigro.

“The facets of the bill that are aimed at building out that security, building that domestic capacity, are going to be beneficial to the industry in the long term,” he said. “Really it’s a question of timing, and whethet or not all the stars are going to align for the industry to be able to deliver product in the time frame written into this legislation.”

It would to nice to treat CC as a "Laissez Faire" issue to be dealt with whenever the "Market" gets its act together...but that's totally inappropriate, so a "Stimulus" is what's called for...unless you're in the CC denial camp.

subsidies that support price stabilization and make things better for the farmers and consumers...what would be your solution and logical outcome in that arena?
