They can’t afford a union made car. Case closed.
Aren't there a lot of non-union made cars sold in the US every year? (Honda, Nissan, Toyota, Hyundai, Subaru, Kia, etc)
Not defending labor or unions but the sticker price of a car is made up of many things, material cost, admin cost etc. The cost of labor is at most 10%. So a $20K you pay about $2K for labor. Even if robots or slaves built the cars a $20K would still cost $18K. There are a lot of misconceptions out there.
