Another anecdotal example - VW. Lower Saxony has 20% of the voting rights and 11.8% of ownership.
Ever heard of Renault? Due to neo-liberal politics the ownership has changed in more recent times, but they have been state owned for a lot of their history.
The disease of neo-liberalism was a contributory factor to the demise of BL and the word neo-liberalism didn't even exist prior to 1982. The writing was not on the wall with BL during the post war years and their products were highly successful. The UK balance of payments was helped not hindered by the predecessor companies - the Rovers, Triumphs, Austins and what-not.
The problem was investment. So in the years when BL was a lot of private companies they could not get investment from the city. This is because London only invests in companies they can asset strip, they don't speak the same banking language as in Germany where banks invest in companies and people.
After the Labour government that preceded Thatcher rescued BL there was a problem due to the lack of investment, however BL did what they could to rise to the challenge despite the difficulties of strikes and useless managers. Then when Thatcher arrived BL was privatised. There was obviously no investment from the conservative government, that is not how they roll. They just wanted to sell the family silver.
So then it comes to the media and how they portray the story as all the fault of the unions and the company being nationalised. Yet the story is not an honest one, the truth is that the UK banking sector just don't invest in actual companies that employ people that do actual work. They might front the cash for some asset stripping or they might invest in property, but never did they invest in UK industry. German culture was different, banks there have much better investment ideas, they can also see a better return from investing in their own concerns.
The disease of neo-liberalism was enforced on the world so you have things like Renault that the state aren't allowed to own if they are to be in the clubs of the EU/IMF/GATT and what not.
The people that manage companies are not automagically better people just because they work for vulture capitalists instead of the government.
