When my kids were young and played a new game, the pattern was clear: If they won, they liked that game and wanted to play it again. If they lost, they didn't like that game. Tyler Cowen once told me how this generalizes; the essential question of ideology is: who should be admired? We tend to think it would be good for the world if policies and culture tilted a bit to more admire the activities that tend to make us look good.
Such disagreements, however, shouldn't distract us from the fact that societies often agree quite a bit on what kinds of activities they admire. For example, Frank and Miller's instinctive fear that the love of stuff obtained from distant soulless others corrupts one's soul is ancient. Greek historian Herodotus ~430BC:
I'm not exactly sure why traders have been so consistently disliked, though I suspect it has something to do with loyalty signaling. But I am pretty sure that while societies consistently prefer to encourage more of the activities they admire, such choices often make them on net worse off. I said two years ago:
Unfortunately, our minds were not built from a global point of view. We are instead built to admire admirable activities, in addition to admiring the people who do them. We admire drawing, singing, sporting, writing, joking, helping, and so on, and we support policies that encourage these activities. We like our families, churches, clubs, companies, cities, and nations to subsidize such activities. Parents push their kids toward more admirable activities, such as music over video games. And nations subsidize science, sport, and arts that will impress other nations.
This support urge can make evolutionary sense. A group that coordinates to help its most noticed members look more admirable may be more admired as a group, to the benefit of all group members. But at a global level we all suffer from admiring admirable activities, much like trees suffer by working to grow tall enough to see the sun past other trees.
Yes trade and traders are often not admired, and so societies often discourage trade. But if we economists know anything it is that overall societies tend to hurt, not help, themselves by discouraging trade.
