It's not so much that the broader market is rigged. It's that every major industrial hub funds its own player: BYD (Shenzhen), NIO (Hefei), GAC Aion (Guangzhou), SAIC (Shanghai), etc. It might seem "rigged" to a westerner because it's so subsidized but China has a LOT of industrial hubs and therefore a lot of competition.

The US also heavily subsidizes EVs but the subsidies mostly only go to one company. Just take a look at the mind-boggling amount of subsidies we've given to Tesla both federally and on a state-by-state basis. Nevada's almost 2$ billion being the most blatant https://subsidytracker.goodjobsfirst.org/parent/tesla-inc

Interesting definition of freedom. The top three countries happen to be the places most permissive to international tax dodgers.
