BBB never passed, and Biden's policies were a hodge-podge of conflicting goals and huge price tags without follow-through. Look how few EV chargers were deployed, how difficult it was to spend IRA and CHIPS funds, etc.
China subsidizes it's industries, but we're also flat out uncompetitive while ALSO subsidizing our stuff. Their budget EVs feel like our luxury models at a fraction of the price. We still kowtow to the 6% of private workers in unions at the expense of the bigger picture.
There is "helping" and there is "coddling;" our auto firms are hopelessly adrift. They will never compete on a global market and only survive due to protectionism. You can hurt the climate by making foreign EV less competitive, but that's a long term loss
CHIPS was hamstrung by tying the new infrastructure to onerous union and environmental requirements that slowed down these projects to a crawl. Now Trump is raiding the corpse of this failure. The Biden administration scrambled to nominally spend the money by the end of his term, but they didn't make much progress.
A good example of the pointlessness of the last four years (from a substance somewhere):
"While the Inflation Reduction Act was reasonably effective at increasing inflation, it was not very effective at accomplishing its more tangible goals. Take green energy infrastructure, for example. The IRA earmarked $7.5 billion to install hundreds of thousands of electric vehicle charging stations. Two years later, you could count how many of these new, federally-funded chargers had been added on two hands: EIGHT.
The reason for the failure was mission creep, or what NYT podcaster Ezra Klein calls “everything bagel liberalism.” It wasn’t enough to spend billions on new chargers, no; the law also needed to make sure those chargers were installed only by unionized workers, that the component parts be made only in America, and that the chargers’ locations satisfy a complicated set of equity requirements."
