wealth - the net gain in material well-being from economic activity. Wealth is measured according to the items of value in a given culture. wealth concentration measure - measures inequality. Percentages, Gini coefficient, ranges are all measures of wealth concentration. wealth distribution - a plot of the wealth held by all the members of a community. Wealth distribution is concerned with the whole population of people. world view - the beliefs about the limits and workings of the world shared by the members of a society and represented in their myths, lore, ceremonies, social conduct, and general values.
On the other hand, the Culture can be seen as fundamentally hedonistic (one of the main objectives for any being, including Minds, is to have fun rather than to be 'useful'). Also, Minds are constructed, by convention, to care for and value human beings. While a General Contact Unit (GCU) does not strictly need a crew (and could construct artificial avatars when it did), a real human crew adds richness to its existence, and offers distraction during otherwise dull periods. In Consider Phlebas it is noted that Minds still find humans fascinating, especially their odd ability to sometimes achieve similarly advanced reasoning as their much more complex machine brains.
