We each have a function.

       Hello fellow people of the world! Society as we know it is changing,  but one thing remains the same. The theory of functionalism is the best and will remain the best way to explain how the machine known as society works. Functionalism is where every individual has his or her own function or duty which contributes to the society as a whole. 
       Some individuals may be teachers others stay at home to take care of their children. The point is, is that every human being has something uniquely different that they contribute to the functioning society. Even if the roles of individuals change the idea that each person is valuable to society stays in tack. For example society needs doctors to save lives, garbage men to keep the planet clean, entertainers to bring joy to depressing situations, and Olympians to push others to achieve their highest goals. Sure their has always been a class struggle between the wealthy and the poor,  but that may end in  the future. The idea of a functioning society will always remain because everyone will always be doing something that contributes to society, whether in a negative or positive way, and is needed for it's survival.
