Policy for abundance and competition matters a lot for China success. It starts with abundant raw material and processing. Steel and construction materials matters to factory building costs in addition to new energy production costs. It's unclear how much of abundance outcomes is the result of direct incentives to material producers/refiners vs "build it and they will come" attitudes that includes confidence in supporting clean energy/vehicles downstream.
In the west, oil oligarchy protectionism drives policy. History of oil companies patting themselves on the back with PR on clean energy while doing nothing. Funding massive disinformation and politicians for climate terrorism, and the solutions/progress that is made outside of oil companies is just extremely slow. Meant for PR and scarcity, and the hopes that high scarcity profits can be dressed up as rewarding national champions doing a little bit against global warming. Most of the IRA is not about creating US abundance, but rather setting up US monopolies in US supply chain, that have caused projects to stall because they are not competitive by US ROI standards, and the lack of confidence in usurping oil oligarchy for US only market.
Article starts off with "do we need domestic industry?" before not making any conclusions about it later. If Aliens came to earth to trade us cheap stuff, US oligarchy would insist on losing a war against the Aliens instead. Cheap energy and materials further makes jobs. Solar especially has up to 90% of its costs as local deployment spending. Cheap energy and materials is core to competitive manufacturing, and low consumer cost of living. The political reaction to go to war with competitive goods to protect domestic oligarchy profits, and pretend to support uncompetitive domestic upstarts with subsidies, is a net social loss. We end up with a high subsidy per job level, where UBI (full society redistribution) would enable more affordability of better products instead.
