YOu speak of this infrastructure as if it fell from the sky. Where has it come from? It comes from the choice and values of the people. Where people have strong preference for complacency and lack of personal initiative, you see tyrant come to power time and time again. In England, because of the deeply rooted respect to the individual freedoms, even the Inquisition failed to be established for almost two centuries (the total number of victims in the two centuries of existence is by a factor of 1000 smaller than those burned at the stake in Spain in a year).
People choose their institutions. And, even if the same institution is imposed on different peoples, it ends up functioning differently because of the divergence of persistent social values.
It is seldom asked: why is it that our constitution is known to the world for two centuries, and yet not a single country adopted anything similar? The French are on their Fifth Republic; in the last century, Germany and Italy were formed; there was an explosion in the number of new countries in 1940s-1960s on the African continent; just recently, the Russian Empire disintegrated into independent states. Not a single one has adopted our consitution. Has it not proved by now its value? Those to whom the value has been proven are flocking to our shores. And the rest? The rest prefer something else.
I most certainly do not. A social and legal infrastructure is not just happenstance. It comes from the inner core of individuals for whom it exists. It's rooted in the hearts of man (as a whole). [...look, I'm not explaining myself very well, but I know what I'm trying to say...anyway, no big deal.]
