> Owners are pushing for the first, labor wants anything except the first.
There are two important actors left out of this analysis: consumers and parts suppliers.
It doesn't fit the evil owner narrative, but often these efficiency gains translate largely to reduced prices for consumers. Consumers vote with their wallets, so it is often the case that unless the evil owners conspire against consumers by fixing prices, businesses are often forced to pass on efficiency gains as cheaper prices.
As for suppliers, a very large portion of an electric car price is in the battery. If the size of the pie is remaining the same, then this new player is taking a lot $$ off the table, offsetting efficiency gains.
