No, it can't. If PRC makers NEEDED low wages to undercut pricing vs west sure. But PRC EVs selling far above domestic MSRP, more than enough to cover wage differential, i.e. lower wages isn't doing the undercutting, it's enabling more profitable extraction. Reality is western competitors are simply not competitive regardless of wage differential when most structural competitiveness come from vertical integration. It doesn't help west is paying more to build worse. And paying less to build worse also not going to close gap.

Can be, but likely aren't to any greater extent than in the West without substantial evidence. And so perhaps it should not be the first reason listed for why it's cheaper when there are perfectly reasonable explanations outside of the constant 'China bad, evil' orientalist shtick that just shows how scared we in the West are of actual competition, accustomed to exploiting the world for half a millennia.
