In many British firms, workers and management still have a "them and us" mentality, maybe a throwback to the British class system, rather than the 1970s? In Europe companies are more often run by cooperation between workers and management, with workers involved in decision making, owning shares in the company and there being a smaller pay gap between those at the bottom and those at the top. German companies can raise capital from regional banks, regional government and regional stock exchanges, rather than via the City as in the U.K. We British should have learnt a lot from the way things are done abroad in the 40+ years that we were in the EU, but we didn't and I can't see that changing any time soon.
Our form of adversarial politics (with opposing sides threatening what they are going to 'do' to the other at election time, and is another manifestation of this 'them' and 'us') doesn't exactly give confidence in long term investment decisions either. We are much more American than German in outlook.
Both systems have their pros and cons, but you can't cherry pick the best of both, which makes changing from one to the other difficult and unlikely.
