Functionalism or Marxism?

I believe functionalism has withstand and will continue to withstand our society because functionalist goals are to maintain social stability, keep society running smoothly, and resolve conflicts. So they believe in everything running smoothly in a society and to solve a problem as soon as it happens instead of the problem lingering and causing bigger problems. Functionlistes magic word is consensus because they're consensus about the goals and values of the social structure. The also believe that the individual has to submit to this higher order, which exists outside themselves which was their before the persons birth and will continue to be with them after death. Marxist view on the other hand believes that the capitalist class shapes the rest of the society which is total b.s in my opinion because people are taught by their parents about how they should act and treat people and not by the capitalist class. So if I was to choose which theory has withstand our society and will continue to withstand our society it'll be Fuctionalism.
