Just ask the Brits. They had unions that make the UAW pale in comparison as far as making demands on their owners. Plus, they were run by people that felt that the priveledged class of the old Empire was still around, and that real negotiations were pointless. Nobody was willing to bend, so they just went broke. Today, there are no real British owned car companies, just cars with old names but new owners.
Rolls Royce, Bentley, Astin-Martin, Jaguar, Range Rover, Mini Cooper, etc.
Every car exported from the UK is made by a foreign owned company. Any irony to the Germans owning RR and Bentley?

The Japs are just as strong there as they are here. The GM and Ford brands are even doing well in Europe, better than in the USA.
