It's important to appreciate this fully.
Agreed.
They had social contracts too, you see.
Agreed. And the Social Contract they had then was different from the one they have now and different from ours.
(Ummm, I seem to have suddenly lost track of what weve been arguing about.)
This time I was being humorous: in Japanese culture, a person of higher standing had the authority to kill anyone of lower social standing for any reason that pleased him. That's not a "contract"; the peasants in this case most certainly never agreed to anything. But if they don't like it, their only choice is to flee Japan. So this obviously unjust institution fits your idea of a "social contract", and the "social contract" in the US has similarly bad implications--for example, that policemen can break into a house, shoot the occupants, explain that they meant to raid the "crack house" next door, and get away with murder. I can't escape this injustice without fleeing the country.
