I was watching YouTube last night. I find it interesting that the subject matter generally falls into various themes, one of which is were the presenter builds a following by having things of value he or she gives away for free. One such is a jewelry store owner who goes out on the streets of various cities and tries to give things away. Many many people would walk right by him when he tried to hand them an one oz. gold bar. He left a silver ingot on the street, I think in New York, which a tourist picked up in a matter of minutes but in Tokyo the only person who picked it up and looked at it put it right back down on the street.
I have heard you can leave your wallet in the middle of the street in Saudi Arabia and come back and get it the next day. On the surface one could say that fear of punishment or fear of shame is what prevents a lot of crime but there is also the question of whether it is morally proper to steal. I think that sometimes it is in dire situations but most of the time not, that there is a basic truth to be had. This leads me to the conclusion that the basic reward for a moral attitude toward the possessions of others is a function of self respect. 'Virtue is its own reward' a saying to which others not so inclined reply, 'virtue is its only reward', but in my opinion, that reward is known only to those who know it and it's huge. What is the value of life to those who have no self respect?
Anyway, my point, I guess, is that some cultures are less thief ridden than others, the difference being the culture itself not the race or genetics of the people.
