Agree. The IRA is a hugely pro-Tesla bill. Tesla will rake in many billions from all its provisions.
While the current administration is very pro-union and therefore somewhat anti-Tesla, the IRA was written to be climate friendly, job friendly, and consumer friendly.
I don't ascribe anti-Tesla malice toward the treasury department for its (rather odd) ruling on Model Y qualification for the tax credit. The Ford Mustang Mach E fares much worse as Ford can't afford to lower prices.
While as an investor, it would be nice if Tesla could capture more of the $7500 through higher prices, this is great for the consumer. Now more people can afford to buy the best EV. And Tesla will happily ramp up production to meet the demand. This is the sort of thing one would hope you could get from a bill like the IRA. It's good for consumers, good for jobs, and good for the planet.
