paywalled. Chinese subsidies for EVs and solar are far less than US ones. China does make sure an abundance of minerals exists, refineries to process them locally. Key industries have access to cheap loans, but often new companies/projects have the same access as leaders. US system favours free money instead which is subject to using it as a slush fund instead of building a successful project that will pay back normal loans.
China's early success on EVs was based on city policies of restricting non EV license plates to certain days of driving. This is free. Having a good charging infrastructure/network also makes EVs an easier decision.
Still, the US is improving enough to get good EV growth, and EV dominance soon enough. Equinox EV is better than model Y. Ford transit van is cheaper electric than ICE, with additional operating cost savings, and as a city vehicle enough range for a full day, and contractor benefits.
US policy is based on pure lies to protect oil oligarchy dominance, but there is still a certainty/path for EV success.
