The subsidies are directly funding Musk's wallet as much or more than they are funding battery research.
Anyone who's been there and done this knows that what the IRS giveth with one hand, the IRS taketh away with the other. The house never loses, and there is no house like the United States Government.

So far, the obvious implication is that at some point in the future Musk will become even more rich, mainly off converting his paper wealth to cash wealth. I cannot get behind the idea of taxpayer wealth being used to make billions of dollars for a few wealthy individuals.
>I'd guess its likely he paid more in taxes than you, if you're an average earner.
Yeah and? I'm talking about 5 bil in subsidies.
