>>10276529^ An important point. The most prosperous societies are high trust. When trust breaks down, socities break down. Japan, Germany, Switzerland, Austria, Sweden, and Norway used to be the only nations where I have ever seen honor based payment systems. In Germany, having those little self-serve shops that residents put up used to be common in many rural areas. Often times, the registers are not even locked. Anyone could just pick it up and walk out with it.
Why won't they?
Honor. It's a concept that is silly and laughable to most people of lower IQ. It requires a degree of impulse control, which is negatively correlated with IQ. It's not silly, because people realize that in a high trust society everybody benefits.
Unsurprisingly, those self-serve shops are becoming increasingly rare, especially whenever migrants move into a town.
