For me it's the same as my view on what everyone buys, which is exploiting child labour to make clothes, shoes, electronic goods, computers, fruit picking, farming etc. It's in everything, and it's abhorrent. More should be done about it, and if that drives up inflation then I'm more than happy to pay that price. Some others can't pay that price though, like all the staff on minimum wage in pubs, shops, who get exploited by everyone in the UK every single day. Could tax the big companies profits more, and peoples high earnings and help out those who are worse off, and supply more foreign aid, I'm all for that too.
It's not the fault of the EV though, that's the fault of the car makers, their suppliers, the governments and everyone who votes for the rich. These EV companies the same companies making ICE vehicles and exploiting child labour everywhere for other aspects, and have been for a century.
They won't be stored, used batteries will be recycled, or reused for the likes of solar storage etc. A used EV battery is still extremely valuable, albeit hard to dismantle at this time, but that will get solved. Do you think there will be used EV batteries in 10 years time stacked up like car shells, at the scrap yard? It won't happen in the EU, as manufacturers are about to be forced to ensure that the batteries become reusable/ recyclable. Nissan, VW and Renault are already doing it, and the others have plans.
