First of all I would choose functionalism because it has to deal with the contemporary philosophy and behaviorism. I think that's a great part of life and in society for people to go with functionalism. Now on Karl Marx they had restrict individuals in the function of social class. The conflict between social class is social change. We have a lot going on about that and a lot could be done about it but not much is. The symbols are technology such as cell phones, tablets, computers, game systems and so on. I would suggest you read a book or take a walk to avoid too much technology because it could ruin your eye sight for one and also cause you to pass out sometimes.
