In the end I see the IRA mostly as a way of subsidizing the increased cost that will come with moving all this stuff out of China, we can also consider that suppliers will have increased pricing power for components/minerals that comply with the requirements. Now add in the MSRP limits.
Minerals will be a truly monumental undertaking. Take graphite as an example that is hugely important in batteries and makes up a big proportion of them, I've seen numbers suggesting China controls something like 80% of all global battery-grade graphite production and North Korea controls 10%. My work is largely consulting with resource companies in Canada and I've done a few mining projects, it is borderline impossible to get anything out of the ground here these days. A new mining project right now, you're probably looking a decade out from engineering to commissioning and actually getting product.
