Culture is society, and includes all people. The leaders at the top are just as much a product of culture as everyone else. To believe that there are people in control of that is to count yourself and everyone else a victim. No one is a victim. No one group is in charge of something as inherent to society as culture. The "programming" you see in television needs an audience to believe it. People are just as responsible for being followers of those who you think are propagating an agenda.
