Just saw the documentary and while it was all interesting and astonishingly self-reflective and and self-critical, I strongly think that the mindset, which is ultimately responsible for the downfall of the British motor industry, is still existing there.
The idea of classes and class consciousness - which to me is the root of all the evil - is still very alive and kicking in Britain. It makes me doubt, that a successfull all-British industry under all-British ownership and management could be possible again... Not because of the workers or the general population but because of the mindset of the intellectual and economical elite.
I mean seriously: Even in their most objective moments, most of those educated, intelligent British chaps can not overcome their tendency to look down on others and make fun of other countries' national peculiarities. Admiration is almost always mixed with mockery, compliments always given with a grain of salt, as if the goal is to steadily convince themselves of still being superior to other despite the dismal realityof today's Britain. It seems to be a natonal reflex - like the constant and very often annoying self-criticism of us Germans.
And as a modern-day European, I have the feeling that the intellectual elite of the British, the part of the country that's responsible for its 21st century route, still think they're something better than the rest of the world. Maybe they should consider, that most of the British population has already arrived in a unified Europe, that the normal British citizen has even become "less British" during the last 20 or 30 years, while the conservative "upper class" still make a clear destinction between "us and them" not only on the national but also on the international level.
