Dick,
In the US they regulate for safety, which explains their superior safety standards.
In Europe they have outcome based regulation. They just can't figure out what outcome they want to achieve.
In Australia we have liability avoidance based regulation.
Thousands of pages and growing every day.
They absolve government of any liability for anything by being a major liability to an industry that must somehow comply with them.
Will our liability avoidance aviation regulations grow bigger than our taxation regulations?
