All social systems are based upon a division of economic roles. The values of a social system are embodied in the prestige accorded persons who fill various economic roles. It is ttherefore unsurprising that, for any social system, the introduction of labor-saving technology that makes certain economic roles obsolete will tend to undermine the values in that social system. Which one of the following can most reasonably be concluded on the basis of the information above? ['A technologically advanced society will place little value on the prestige associated with an economic role.', 'No type of technology will fail to undermine the values in a social system.', 'Social systems will have unchanging values if they are shielded from technological advancement.', 'A social system whose values are not susceptible to change would not be one in which technology can eliminate economic roles.']
