This is rather like my observation about British car companies in the late 20th century:
- large factory of British workers + British management: strife, strikes, disaster, bankruptcy (British Leyland)
- small factory of British workers + British management: success, on a small scale (lots of the F1 industry, McLaren etc; also true of non-car manufacturing)
- large factory of British workers with overseas management: success (Nissan Sunderland, BMW era Mini, etc)
Where does someone like Rover fit in to your matrix? If I can respectfully recommend. If you can go have a read of "We sell our time no more" by Paul Stewart.
Tory governance and fiscal policies had all the responsibility for Leyland, Hillman and more importantly Rover.
