Why didn't the prices of cars actually just go down when the labor became so much cheaper? What were those union workers making in Michigan in the 70's? It was a whole lot more than Mexicans and Chinese earn today --- so why the jump from $3000-$4000 way up to $30,000? It's not just the air-conditioners --- and cars in the past were made of metal, today they're mostly plastic.
Why didn't the prices rise when all the new features were added?
