The UK does have a saner union and left wing tradition, but the old shop floor naturally selected for bully boy types. When put up against the emotionally handicapped public school victims in management, adversarial relationships were inevitable.

Thatcher eliminated the bully boys and gave the managers free reign. But the problem isn't so much with any particular class, as an overall culture of competitive selfishness and lack of generosity.

You won't get interdependence and cooperation from people who find the idea of interdependence personally offensive.
